# 1460. Make Two Arrays Equal by Reversing Sub-arrays

<https://leetcode.com/problems/make-two-arrays-equal-by-reversing-sub-arrays>

## Description

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 = [7], arr = [7]
**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`
