+# 1460 - Make Two Arrays Equal by Reversing Subarrays (Easy)
+
+## Problem Link
+
+https://leetcode.com/problems/make-two-arrays-equal-by-reversing-subarrays/
+
+## Problem Statement
+
+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:**
+
+```
+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 subarray [2,4,1], arr becomes [1,4,2,3]
+2- Reverse subarray [4,2], arr becomes [1,2,4,3]
+3- Reverse subarray [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.length`
+- `1 <= target.length <= 1000`
+- `1 <= target[i] <= 1000`
+- `1 <= arr[i] <= 1000`
+
+## Approach 1: Sorting
+
+- Time Complexity: $O(n log n)$
+- Space Complexity: $O(log n)$
