+# is-valid-array-subsequence
+
+Created by [@Divlo](https://github.com/Divlo) on 23 April 2022.
+
+## Instructions
+
+Given two non-empty arrays of integers, write a function that determines whether the second array is a subsequence of the first one.
+
+A subsequence of an array is a set of numbers that aren't necessarily adjacent in the array but that are in the same order as they appear in the array. For instance, the numbers `[1, 3, 4]` form a subsequence of the array `[1, 2, 3, 4]`, and so do the numbers `[2, 4]`. Note that a single number in an array and the array itself are both valid subsequences of the array.
+
+### Input
+
+- **Line 1:** `array` Integers separated by spaces
+- **Line 2:** `sequence` Integers separated by spaces
+
+### Output
+
+The output should return `true` if the `sequence` is a subsequence of `array` and `false` otherwise.
+
+## Examples
+
+See the `test` folder for examples of input/output.
+
+### Example 1
+
+#### Input
+
+```txt
+5 1 22 25 6 -1 8 10
+1 6 -1 10
+```
+
+#### Output
+
+```txt
+true
+```
+
+### Example 2
+
+#### Input
+
+```txt
+5 1 22 25 6 -1 8 10
+5 1 22 25 6 -1 8 10 12
+```
+
+#### Output
+
+```txt
+false
+```
