Error

You are given an array **Arr** of size **N**. Find the sum of distinct elements in an array.

**Example 1:**

**Input:
**N = 5
Arr[] = {1, 2, 3, 4, 5}
**Output: **15
**Explanation:** Distinct elements are 1, 2, 3
4, 5. So sum is 15.

**Example 2:**

**Input:
**N = 5
Arr[] = {5, 5, 5, 5, 5}
**Output:** 5
**Explanation: **Only Distinct element is 5.
So sum is 5.

**Your Task:**

You don't need to read input or print anything. Your task is to complete the function **findSum()** which takes the array of integers **arr **and **n**** **as parameters and returns an integer denoting the answer.

**Expected Time Complexity:** O(N*logN)

**Expected Auxiliary Space:** O(N*logN)

**Constraints:**

1 ≤ N ≤ 10^{7}

0 ≤ A[i] ≤ 10^{3}
