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.
