Input: $str = "abccccd"
Output: "cccc"

Example 2

Input: $str = "aaabcddddeefff"
Output: "aaa", "dddd", "fff"

Example 3

Input: $str = "abcdd"
Output: ""

Task 2: Reverse Equals

Submitted by: Roger Bell_West

You are given two arrays of integers, each containing the same elements as the other.

Write a script to return true if one array can be made to equal the other by reversing exactly one contiguous subarray.

Example 1

Input: @source = (3, 2, 1, 4)
       @target = (1, 2, 3, 4)
Output: true

Reverse elements: 0-2

Example 2

Input: @source = (1, 3, 4)
       @target = (4, 1, 3)
Output: false

Example 3

       @target = (2)
Output: true
