The XOR Gate
Basic Accuracy: 61.46% Submissions: 96 Points: 1

Given N bits to an XOR - Gate find the output that will be produced.
XOR - Gate Table:
1 ^ 1 = 0
1 ^ 0 = 1
0 ^ 1 = 1
0 ^ 0 = 0

Example 1:

Input:
N = 4
arr: 1 1 1 0
Output:
1
Explanation:
1 ^ 1 = 0
0 ^ 1 = 1
1 ^ 0 = 1
hence output is 1

Example 2:

Input:
N = 4
arr: 0 0 1 0
Output:
1
Explanation:
0 ^ 0 = 0
0 ^ 1 = 1
1 ^ 0 = 1
hence output is 1

You don't need to read input or print anything. Your task is to complete the function xorGate() which takes the array arr[], its size N as input parameters and returns the output after processing OR operations on N bits.

Expected Time Complexity: O(N)
Expected Space Complexity: O(1)

1<=N<=1000
