The AND Gate
Basic Accuracy: 30.77% Submissions: 39 Points: 1

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

 

Example 1:

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

Example 2:

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


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

 

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