Given two given arrays of equal length, Check if given arrays are equal or not.

**Problem Note**

- Two arrays are said to be equal if both of them contain the same set of elements, the permutation of the elements may be different though.
- If there are repetitions, then counts of repeated elements must also be the same for two arrays to be equal.

**Example 1**

```
Input: A[] = [3, 8, 9, 1] , B[] = [9, 3, 1, 8]
Output: 1
```

**Example 2 **

```
Input: A[] = [1, 2, 5, 2, 1] , B[] = [2, 1, 2, 1, 5]
Output: 1
```

**Example 3 **

```
Input: A[] = [1, 2, 2, 7, 1] , B[] = [2, 1, 2, 7]
Output: 0
```

**Example 4 **

```
Input: A[] = [0, 5, 0] , B[] = [5, 0, 5]
Output: 0
```
