+
+Hello! 👋
+
+Welcome to the Ultimate Guide to master `git` in your daily workflow, we will see what are the most used commands, what are the best practices, and tips and tricks.
+
+This guide is a summary of the most important things to know when working with `git`, and in general, will link to the official documentation of `git` or other resources for more details, it is on purpose to not go in depth in each topic, it allows to summarize `git` and vocabulary about it (you can use it as a `git` cheatsheet).
+
+**Note:** Sources used to write this blog post are available at the [end of this post](#sources).
+
+## Introduction
+
+**Git** is a free and open-source distributed **version control system** for keeping track of changes across a set of files.
+
+Git was originally authored by [Linus Torvalds](https://en.wikipedia.org/wiki/Linus_Torvalds) in 2005 for the development of the [Linux kernel](https://kernel.org/).
+
+Git allows:
+
+- to work with several people on the same codebase.
+- track changes to know who did what and when.
+- revert changes.
+
+Git is **decentralized**, which means that every developer has a full copy of the repository and the complete history of the project.
+
+## Get started with `git` and `.gitconfig` config file
+
+The first thing you should do when you install Git is to set your user name and email address.
+
+```sh
+git config --global user.name "Username"
+git config --global user.email "email@example.com"
+```
+
+These configurations are stored in the `.gitconfig` file in your home directory (e.g: `~/.gitconfig`) with this format:
+
+```sh
+[user]
+  name = Username
+  email = email@example.com
+```
+
+You can find more information and useful `git` configurations in the [official documentation](https://git-scm.com/docs/git-config).
+
+## How `git` works?
+
+Each `git` project is called a **repository** (or **repo** for short) and it contains all the files and folders for a project, as well as each file's revision history (**commits**) stored in the `.git` folder.
+
+The history of a repository is represented by a graph.
+
+Each node is called commit and contains:
+
+- an instantaneous view (snapshot) of the state of the repository at a specific moment
+- metadata: message, author, creation date, etc.
+
+Commits are **snapshots** (not diffs on each file) of the project at specific moments in time.
+
+There are several areas where the files in your project will live in Git:
+
+- **Working directory**: the files that you see in your computer's file system.
+- **Staging area**: the files that will go into your next commit (files added with `git add <filename>` command).
+- **Local repository**: the `.git` directory, which contains all of your project's commits, branches, etc. (files added with `git commit -m "message"` command).
+- **Remote repository**: the `.git` directory in a remote server (files added with `git push` command).
+
+## Commands cheatsheet
+
+You can find the official documentation of `git` commands at [git-scm.com/docs](https://git-scm.com/docs).
+
+```sh
+# Initialize a new git repository
+git init
+
+# Clone a repository
+git clone <url>
+
+# Add all the files to staging area
+git add .
+
+# Add specific file to staging area
+git add <file>
+
+# Commit changes
+git commit -m "chore: initial commit"
+
+# Add remote repository
+git remote add <remote> <url>
+# The main <remote> is often called `origin`
+
+# Add forked repository
+git remote add <remote> <url>
+# The forked <remote> is often called `upstream`
+
+# List all the remotes
+git remote
+
+# Sync forked repository
+git fetch <remote>
+git merge <remote>/<branch>
+
+# Push changes to remote repository
+git push <remote>
+
+# Pull changes from remote repository
+git pull <remote>
+
+# Show the status of the working tree
+git status
+
+# Show the commit history
+git log
+
+# Create a new branch
+git checkout -b <branch>
+
+# Switch to a branch (or tag or commit)
+git checkout <branch>
+
+# Merge a branch into the current branch
+git merge <branch>
+
+# Combine multiple commits of a branch into one for a merge
+git merge --squash <branch>
+
+# Change several past commits (interactive rebase)
+# HEAD points to the current consulted commit.
+git rebase --interactive HEAD~<number-of-commits>
+
+# Delete a branch
+git branch --delete <branch>
+git push <remote> --delete <branch>
+
+# Fetch branches from remote repository and prune
+git fetch --prune
+
+# Revert a commit
+git revert <commit>
+
+# Reset the current branch, delete all commits since <branch> (without removing the changes)
+git reset --soft <branch>
+
+# Apply the changes introduced by some existing commits
+# (by first being on the branch where you want to apply the commit)
+git cherry-pick <commit>
+```
+
+## `.gitignore` file
+
+The `.gitignore` file is a text file that tells `git` which files (or patterns) it should ignore.
+
+The `.gitignore` file is usually placed in the root directory of the repository.
+
+We usually ignore files that are generated by the build process or files that contain sensitive information.
+
+Example of `.gitignore` file:
+
+```sh
+.env
+build
+*.exe
+```
+
+## `.gitkeep` file
+
+The `.gitkeep` file is a file that is used to keep an empty directory in a Git repository.
+
+This is useful when you want to keep an empty directory in your repository but you don't want to commit any file inside it.
+
+## Git remote repositories (GitHub/GitLab)
+
+Once you are ready to share your code over the internet, you will need to create a remote repository on a service like [GitHub](https://github.com) or [GitLab](https://gitlab.com).
+
+There are many other services, you can also self-host your own Git server.
+
+### SSH vs HTTPS authentication
+
+Once you have created a remote repository, you will need to authenticate to push and pull changes.
+
+There are two main ways to authenticate:
+
+- **SSH**: you will need to generate an SSH key pair and add the public key to your remote repository.
+- **HTTPS**: you will need to provide your username and password each time you push or pull changes.
+
+SSH authentication is the recommended way to authenticate to a remote repository.
+
+You can find more information about SSH authentication in the [official documentation](https://git-scm.com/book/en/v2/Git-on-the-Server-Generating-Your-SSH-Public-Key).
+
+### Sign `git` commits with `gpg`
+
+As we have seen in the [Get started with `git` and `.gitconfig` config file](#get-started-with-git-and-gitconfig-config-file) section, we can configure `git` with a name and email address with a value of our choice.
+
+That means that **anyone can create a commit with any name and email address and claim to be whoever they want** when they create a commit.
+
+To avoid this, you can sign your commits with a <abbr title="GNU Privacy Guard">[GPG](https://gnupg.org/)</abbr> key.
+
+You can find more information about signing commits in the [official documentation](https://git-scm.com/book/en/v2/Git-Tools-Signing-Your-Work).
+
+### Continous Integration/Continuous Delivery (CI/CD)
+
+Once you have your code in a remote repository, everyone (with access) can potentially start contributing to the project. This is great, but it also means that you need to have a way to ensure that your code is working as expected for each change in the project.
+
+You could do it manually, depending on the size and the complexity of the project, but it could be a tedious task.
+
+Instead, you can use a **Continuous Integration** (CI) service to automate the process of testing your code, running linting, unit tests, e2e tests, etc.
+
+There are many CI services, but the most popular ones are [GitHub Actions](https://github.com/features/actions), [GitLab CI](https://docs.gitlab.com/ee/ci/), [CircleCI](https://circleci.com/), [Travis CI](https://travis-ci.org/), and many others...
+
+Then, once your code is ready, tested and working as expected, you can use a **Continuous Delivery** (CD) service to automate the process of **deploying your code**.
+
+CI/CD services are usually integrated with remote repositories, so you can configure them to run automatically when you push changes to the remote repository.
+
+## Best practices and `git` workflows
+
+Commit messages are very important, they are a way to easily know what has changed in the project.
+
+There are many conventions for commit messages, but the most popular one is the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) specification.
+
+Then, we can use the commit messages to automatically determine a [semantic version](https://semver.org/) for the next release of the project.
+
+When multiple developers are working on the same project, it is important to organize the work in a way that everyone can work on different features without conflicts (changes in the same files).
+
+There are many ways to organize the work, but the most popular ones are:
+
+- [GitFlow](https://nvie.com/posts/a-successful-git-branching-model/)
+- [GitHub Flow](https://guides.github.com/introduction/flow/)
+- [Trunk-based development](https://trunkbaseddevelopment.com/)
+
+They are called **Git workflows**, or **Git branching strategies**.
+
+## Conclusion
+
+`git` is the tool that every programmer should know to do collaborative work (not only, `git` is also very powerful even when working alone) and keep track of changes across a set of files.

+
+Hello! 👋
+
+As **performance** and **reliability** is more and more important in software development, it is important to know how to write **efficient code**, and also learn to **not rely on every possible dependency of the world**, when it is not worth it.
+
+The more dependencies we add to our projects, the greater the complexity and maintenance overhead becomes. Each additional dependency requires understanding its functionality, <abbr title="Application Programming Interface">API</abbr>, and potential conflicts with other dependencies. This complexity makes the codebase harder to maintain, and it also poses significant security risks.
+
+We don't want to "reinvent the wheel" and rewrite everything from scratch for each project. In fact, you are **always depending on something** when you are writing your software. At the very least, you are dependent on the programming language you are using. Even if you are doing very low-level stuff, you are still depending on something: hardware.
+
+However, it is important to draw a line between what dependencies are worth the cost and which are not.
+
+Most likely adding a [JavaScript npm package `is-odd`](https://www.npmjs.com/package/is-odd) to check if a number is odd or even for example, is not worth it. Writing it ourselves is easier and allows a better maintenance in the long term.
+
+Learning **how to solve problems** and how to write efficient code is very important and also a very broad and complicated topic, so this blog post will only be an **introduction to the subject**, and will not go in depth.
+
+**Note:** Sources used to write this blog post are available at the [end of this post](#sources).
+
+## What is Competitive Programming?
+
+**Competitive programming** consists of solving correctly and efficiently **well-defined problems** by writing **computer programs** under specified **constraints**. Typically a solution to a problem is a combination of well-known techniques and new insights.
+
+There are many famous competitions: [Google Code Jam](https://codingcompetitions.withgoogle.com/codejam), [Facebook Hacker Cup](https://www.facebook.com/codingcompetitions/hacker-cup), [International Olympiad in Informatics](https://ioinformatics.org/), [International Collegiate Programming Contest](https://icpc.global/), [LeetCode](https://leetcode.com/), [CodinGame](https://www.codingame.com/), etc.
+
+The most common programming languages used for Competitive Programming are: **C++**, **Python** and **Java**. However the design of the algorithms and data structures are applicable to **any programming language**.
+
+All examples solutions on this blog post will be done in **Python**.
+
+## Topics to explore/learn with Competitive Programming
+
+- Time/Space complexity and Big O Notation
+
+- Sorting: Sorting algorithms and Binary search
+
+- Data structures: Arrays (1D, 2D: Matrix, 3D, Multidimensional), Dictionaries, Linked lists, Stack, Queue, Trees, Graphs, Heaps, etc.
+
+- Complete search: Generating Subsets, Permutations, Combinations, etc.
+
+- Greedy algorithms: Coin problem, Scheduling, Minimizing sums, etc.
+
+- Dynamic programming: Fibonacci, Coin problem, Knapsack, etc.
+
+- Bit manipulation: Bit representation, Bit operations, etc.
+
+- Shortest path: Dijkstra, Bellman-Ford, Floyd-Warshall, etc.
+
+- String: Trie structure, String hashing, Z-algorithm, etc.
+
+You can see there are lot of concepts to learn and explore, and it is not an exhaustive list. On this blog post, we will only see the first topic: **Time/Space complexity and Big O Notation**.
+
+## Time/Space complexity and Big O Notation
+
+### Definition
+
+An Algorithm is a finite sequence of well-defined instructions, that have to be given to the computer to perform a specific task. In this context, the variation can occur the way how the instructions are defined. There can be **any number of ways**, a specific set of instructions can be defined **to perform the same task**. Also, with options available to choose any one of the available programming languages, the instructions can take any form of syntax along with the performance boundaries of the chosen programming language. We also indicated the algorithm to be performed in a computer, which leads to the next variation, in terms of the operating system, processor, hardware, etc. that are used, which can also influence the way an algorithm can be performed.
+
+Different factors can influence the outcome of an algorithm being executed, it is wise to understand how efficiently such programs are used to perform a task. To gauge this, we require to evaluate:
+
+- The **Space complexity** of an algorithm **quantifies** the amount of **space or memory taken** by an algorithm to run based on the size of the input.
+- The **Time complexity** of an algorithm **quantifies** the amount of **time taken** by an algorithm to run based on the size of the input.
+
+We more often talk about the **time complexity** than space complexity of an algorithm, because we can reuse memory unlike time and memory is cheap nowadays.
+
+**Big O Notation** describes the complexity of an algorithm in terms of **how quickly it grows relative to the input size $n$ (e.g: length of the string, size of the array etc.)** by defining the $N$ number of operations that are done on it.
+Example of Big O notation: $O(n^2)$.
+
+### Time complexity
+
+Time complexity **measures** the **time taken** **to execute each statement** of code in an algorithm. It is not going to examine the total execution time of an algorithm. Rather, it is going to give information about the variation (increase or decrease) in execution time when the number of operations (increase or decrease) in an algorithm.
+
+There are many rules to calculate the time complexity of an algorithm.
+
+#### Loops
+
+A common reason why an algorithm is slow is that it contains many loops that go through the input. The more nested loops the algorithm contains, the slower it will run.
+
+If there are $k$ nested loops, the time complexity of the algorithm will be $O(n^k)$.
+
+##### Example $O(n)$
+
+```python
+for iteration in range(n):
+    pass
+
+# or with a while loop
+iteration = 0
+while iteration < n:
+    pass
+```
+
+##### Example $O(n^2)$
+
+```python
+for iteration in range(n):
+    for iteration2 in range(n):
+        pass
+```
+
+##### Example $O(n^3)$
+
+```python
+for iteration in range(n):
+    for iteration2 in range(n):
+        for iteration3 in range(n):
+            pass
+```
+
+etc.
+
+#### Order of magnitude
+
+A time complexity does not tell us the exact number of times the code inside a loop is executed, but it only shows the **order of magnitude**.
+
+In the following examples, the time complexity of the algorithms is $O(n)$ but the number of operations is different.
+
+##### Example 1
+
+```python
+for iteration in range(0, n * 3, 1):
+    pass
+```
+
+Number of operations: $3n$
+
+##### Example 2
+
+```python
+for iteration in range(0, n + 5, 1):
+    pass
+```
+
+Number of operations: $n + 5$
+
+##### Example 3
+
+```python
+for iteration in range(0, n, 2):
+    pass
+```
+
+Number of operations: ${n \over 2}$
+
+#### Phases
+
+If the algorithms consists of consecutive phases, the total time complexity is the largest time complexity of a single phase because it is usually the bottleneck of the code.
+
+The following code consists of 3 phases, with time complexities $O(n)$, $O(n^2)$ and $O(n)$. Thus the total time complexity is $O(n^2)$.
+
+```python
+for iteration in range(n):
+    pass
+
+for iteration in range(n):
+    for iteration2 in range(n):
+        pass
+
+for iteration in range(n):
+    pass
+```
+
+#### Several variables
+
+Sometimes the time complexity depends on several factors. In this case, the time complexity formula contains several variables: $O(nm)$.
+
+```python
+for iteration in range(n):
+    for iteration2 in range(m):
+        pass
+```
+
+#### Recursion
+
+The time complexity of a recursive function depends on the number of times it is called and the time complexity of a single call. The total time complexity is the product of these values.
+
+##### Example 1
+
+The call `recursive(n)` causes $n$ calls and the time complexity of each call is $O(1)$. Thus the total time complexity is $O(n)$.
+
+```python
+def recursive(n: int):
+    if n != 1:
+        recursive(n - 1)
+```
+
+##### Example 2
+
+```python
+def recursive(n: int):
+    if n != 1:
+        recursive(n - 1)
+        recursive(n - 1)
+```
+
+In this case, `recursive(n)` causes 2 other calls except for $n = 1$.
+
+The following table shows the function calls produced by this single call:
+
+| function call | number of calls |
+| ------------- | --------------- |
+| $g(n)$        | $1$             |
+| $g(n - 1)$    | $2$             |
+| $g(n - 2)$    | $4$             |
+| ...           | ...             |
+| $g(1)$        | $2^{n - 1}$     |
+
+Based on this, the time complexity is:
+
+$$
+1 + 2 + 4 + ... + 2^{n - 1} = 2^n - 1 = O(2^n)
+$$
+
+#### Complexity Classes (from fastest to slowest)
+
+![Big O Notation](../public/images/posts/programming-challenges/big-o-chart-notations.webp)
+
+Here is a list of classes of functions that are commonly encountered when analyzing the running time of an algorithm.
+
+- $O(1)$: **Constant** (does not depend on the input size). A typical constant-time algorithm is a direct formula that calculates the answer.
+
+- $O(\log_2(n))$: **Logarithmic** algorithm often halves the input size at each step. $\log_2(n)$ equals the number of times $n$ must be divided by 2 to get 1.
+
+- $O(\sqrt{n})$: **Square root** algorithm is slower than $O(\log_2(n))$ but faster than $O(n)$.
+
+- $O(n)$: **Linear** algorithm goes through the input a constant number of times. This is often the best possible time complexity, because it is usually necessary to access each input element at least once before reporting the answer.
+
+- $O(n \log_2(n))$: **Log linear** often indicates that the algorithm sorts the input, because the time complexity of efficient sorting algorithms is $O(n \log_2(n))$. Another possibility is that the algorithm uses a data structure where each operation takes $O(\log_2(n))$ time.
+
+- $O(n^2)$: **Quadratic** algorithm often contains 2 nested loops. It is possible to go trough all pairs of the input elements in $O(n^2)$ time.
+
+- $O(n^3)$: **Cubic** algorithm often contains 3 nested loops. It is possible to go trough all triplets of the input elements in $O(n^3)$ time.
+
+- $O(2^n)$: **Exponential** often indicates that the algorithm iterates through all subsets of the input elements. For example, the subsets of $\{1, 2, 3\}$ are $S = \{\{\empty\}, \{1\}, \{2\}, \{3\}, \{1, 2\}, \{1, 3\}, \{2, 3\}, \{1, 2, 3\} \}$.
+
+- $O(n!)$: **Factorial** often indicates that the algorithm iterates through all permutations of the input elements. For example, the permutations of $\{1, 2, 3\}$ are $P = \{\{1, 2, 3\}, \{1, 3, 2\}, \{2, 1, 3\}, \{2, 3, 1\}, \{3, 1, 2\}, \{3, 2, 1\} \}$.
+
+### Estimating efficiency
+
+By checking the time complexity of an algorithm, it is possible to check before implementing the algorithm,that it is efficient enough for the problem.
+
+Example: assume that the time limit for a problem is 1 second and the input size is $n = 10^5$. If the time complexity is $O(n^2)$, the algorithm will perform about $(10^5)^2 = 10^{10}$ operations.
+
+Given that a modern computer can perform some hundred of millions of operations per second. This should take at least 10 seconds, so the algorithm seems to be too slow for solving the problem.
+
+## Practical problem: Maximum subarray sum
+
+There are often several possible algorithms for solving a problem such that their time complexities are different. This section discusses a classic problem that can be solved using several different algorithmic techniques, including brute force, divide and conquer, dynamic programming, and reduction to shortest paths, each technique with different time complexity.
+
+**Maximum subarray sum**: Given an array of $n$ integers, find the contiguous subarray with the largest sum.
+
+Contiguous subarray is any sub series of elements in a given array that are contiguous ie their indices are continuous. The problem is interesting when there may be negative values in the array, because if the array only contains positive values, the maximum subarray sum is basically the sum of the array (the subarray being the complete array).
+
+### Example 1
+
+#### Input
+
+```txt
+[1, 2, 3, 4, 5, 6]
+```
+
+#### Output
+
+```txt
+21
+```
+
+**Explanation:** The subarray with the largest sum is the array itself (as there is no negative values) `[1, 2, 3, 4, 5, 6]` which has a sum of `21`.
+
+### Example 2
+
+#### Input
+
+```txt
+[-1, 2, 4, -3, 5, 2, -5, 2]
+```
+
+#### Output
+
+```txt
+10
+```
+
+**Explanation:** The subarray with the largest sum is `[2, 4, -3, 5, 2]` which has a sum of `10`.
+
+### Worst solution: Brute force
+
+```python
+def maximum_subarray_sum_cubic(array: list[int]) -> int:
+    """
+    Time complexity: O((array_length)^3)
+
+    We go through all possible subarrays, calculate the sum in each subarray and maintain the maximum sum.
+    """
+    if len(array) == 0:
+        return 0
+    best_sum = array[0]
+    length = len(array)
+    for i in range(length):
+        for j in range(i, length):
+            sum = 0
+            for k in range(i, j + 1):
+                sum += array[k]
+            if sum > best_sum:
+                best_sum = sum
+    return best_sum
+```
+
+### Better solution: Linear time
+
+```python
+def maximum_subarray_sum_linear(array: list[int]) -> int:
+    """
+    Time complexity: O(array_length)
+
+    We loop through the array and for each array position, we calculate the maximum sum of a subarray that ends at that position. After this, the answer for the problem is the maximum of those sums.
+    """
+    if len(array) == 0:
+        return 0
+    best_sum = array[0]
+    length = len(array)
+    sum = 0
+    for i in range(length):
+        sum = max(array[i], sum + array[i])
+        best_sum = max(best_sum, sum)
+    return best_sum
+```
+
+## Conclusion
+
+Problems solving is a very complicated and large topic, and also a very important skill to have as a software developer.
+
+To improve our problems solving skills, we can regularly practice with [programming challenges](https://github.com/theoludwig/programming-challenges).
