Make Two Arrays Equal by Reversing Subarrays

You are given two integer arrays of equal length target and arr. In one step, you can select any non-empty subarray 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
Inputtarget = [1,2,3,4], arr = [2,4,1,3]
Outputtrue
You can reverse subarrays of arr to transform it into target, such as reversing [2,4,1], then [4,2], then [4,3].
Example 2
Inputtarget = [7], arr = [7]
Outputtrue
arr is already equal to target without any reverses.

Constraints

  • target.length == arr.length
  • 1 <= target.length <= 1000
  • 1 <= target[i] <= 1000
  • 1 <= arr[i] <= 1000
