Given an integer array of **N** elements. You need to find the sum of two elements such that sum is closest to zero.

**Example 1:**

**Input:**
N = 3
arr[] = {-8 -66 -60}
**Output:** -68
**Explanation**: Sum of two elements closest to
zero is -68 using numbers -60 and -8.

â€‹**Example 2:**

**Input**:
N = 6
arr[] = {-21 -67 -37 -18 4 -65}
**Output:** -14
**Explanation**: Sum of two elements closest to
zero is -14 using numbers -18 and 4.

**Your Task:**

You don't need to read input or print anything. You just need to complete the function **closestToZero() **which takes an array arr[] and its size n as inputs and returns the sum closest to zero that can be formed by summing any two elements in the array.

**Expected Time Complexity: **O(NlogN).

**Expected Auxiliary Space: **O(1).

**Constraints:**

1 ≤ N ≤ 10^{3}

-10^{6} ≤ a[i] ≤ 10^{6}
