1460. Make Two Arrays Equal by Reversing Subarrays
Array, Hash Table, Sorting, AMateList ·Problem Statement
link: LeetCode.cn LeetCode 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:
Input: target = [1,2,3,4], arr = [2,4,1,3]
Output: true
Input: target = [7], arr = [7]
Output: true
Input: target = [3,7,9], arr = [3,7,11]
Output: false
Constraints: target.length == arr.length 1 <= target.length <= 1000 1 <= target[i] <= 1000 1 <= arr[i] <= 1000
