##### Submissions: 6555   Accuracy: 32.7%   Difficulty: Easy   Marks: 2

Given an unsorted array of integers and a sum. The task is to count the number of subarray which adds to the given sum.

Example 1:

```Input:
N = 5
arr[] = {10,2,-2,-20,10}
sum = -10
Output: 3
Explanation: Subarrays with sum -10 are:
[10, 2, -2, -20], [2, -2, -20, 10] and
[-20, 10].
```

Example 2:

```Input:
N = 6
arr[] = {1,4,20,3,10,5}
sum = 33
Output: 1
Explanation: Subarray with sum 33 is:
[20,3,10].```

This is a function problem. You only need to complete the function subArraySum() that takes arr, n, sum as parameters and returns the count of subarrays which adds up to the given sum.

Constraints:
1 <= N <= 105
-105 <= arr[i] <= 105
-105 <= sum <= 105
