Find the remainder
Basic Accuracy: 17.14% Submissions: 35 Points: 1

Given a number N in the form of string, your task is to find the remainder when the number is divided by 7.

Note: The given number is very large and so the Input is taken as a String.

Example 1:

Input:
N = "98"
Output:
0
Explanation:
98 when divided by 7 gives a
remainder of 0.

Example 2:

Input:
N = "13"
Output:
6
Explanation:
13 when divided by 7 gives a
remainder of 6.

You don't need to read input or print anything. Your task is to complete the function findRemainder() which takes a String N as input and returns the answer.

Expected Time Complexity: O(|N|)
Expected Auxiliary Space: O(|N|)

Constraints:
0 <= |N| <= 103
