Difference between sums of odd and even digits
Basic Accuracy: 46.51% Submissions: 114 Points: 1

Given a number S in the form of string, the task is to check whether the sum of digits at odd places is equal to the sum of digits at even places or not.

Example 1:

Input: S = "132"
Output: 1
Explanation: The sum of digits at odd
places is 1+2=3. Similarly the sum of
digits at even places is 3. Since they
are equal,the answer is 1.

Example 2:

Input: S = "123"
Output: 0
Explanation: The sum of digits at odd
places is 1+3=4. The sum of digits at
even places is 2. Since,the sums are
not equal,Thus answer is 0.

You don't need to read input or print anything.Your task is to complete the function oddAndEven() which takes an integer S (in the form of string) as input parameter and returns 1 if the sum of digits at odd places is equal to the sum of digits at even places.Otherwise, it returns 0.

Expected Time Complexity:O(|S|)
Expected Auxillary Space:O(1)

1≤ |S| ≤ 105
