1460. Make Two Arrays Equal by Reversing Sub-arrays

#### QUESTION:

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 = , arr = 
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
``````

#### SOLUTION:

``````class Solution {
public boolean canBeEqual(int[] target, int[] arr) {
Arrays.sort(target);
Arrays.sort(arr);
for(int i = 0;i<target.length;i++)
if(target[i]!=arr[i]) return false;
return true;
}
}
``````
