1460. Make Two Arrays Equal by Reversing Sub-arrays

https://leetcode.com/problems/make-two-arrays-equal-by-reversing-sub-arrays

Description

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:

**Input:** target = [3,7,9], arr = [3,7,11]
**Output:** false
**Explanation:** arr doesn't have value 9 and it can never be converted to target.

Example 5:

**Input:** target = [1,1,1,1,1], arr = [1,1,1,1,1]
**Output:** true

Constraints:

• target.length == arr.length

• 1 <= target.length <= 1000

• 1 <= target[i] <= 1000

• 1 <= arr[i] <= 1000
