Given a number N, find the remainder when the first digit of N is divided by its last digit.
Input: N = 1234 Output: 1 First digit = 1 Last digit = 4 Remainder = 1 % 4 = 1 Input: N = 5223 Output: 2 First digit = 5 Last digit = 3 Remainder = 5 % 3 = 2
Approach: Find the first digit and the last digit of the number. Find then the remainder when the first digit is divided by the last digit.
Below is the implementation of the above approach:
