public final class Solution1460 - Make Two Arrays Equal by Reversing Sub-arrays\.
Easy
You are given two integer arrays of equal length
targetandarr. In one step, you can select any non-empty sub-array ofarrand reverse it. You are allowed to make any number of steps.Return
trueif you can makearrequal totargetorfalseotherwise.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 = 3,7,9, arr = 3,7,11
Output: false
Explanation: arr does not have value 9 and it can never be converted to target.
Constraints:
target.length == arr.length1 <= target.length <= 10001 <= target[i] <= 10001 <= arr[i] <= 1000
