描述
Given two integer arrays of equal length target and arr.
In one step, you can select any non-empty sub-array of arr and reverse it. You are allowed to make any number of steps.
Return True if you can make arr equal to target, or False otherwise.
Example 1:
Input: target = [1,2,3,4], arr = [2,4,1,3]
Output: true
Explanation: You can follow the next steps to convert arr to target:
1- Reverse sub-array [2,4,1], arr becomes [1,4,2,3]
2- Reverse sub-array [4,2], arr becomes [1,2,4,3]
3- Reverse sub-array [4,3], arr becomes [1,2,3,4]
There are multiple ways to convert arr to target, this is not the only way to do so.
Example 2:
Input: target = [7], arr = [7]
Output: true
Explanation: arr is equal to target without any reverses.
Example 3:
Input: target = [1,12], arr = [12,1]
Output: true
Example 4:
