C: Hours, minutes and seconds

Split a number of seconds into a time.

What to build

A program that uses division and remainders together.

Requirements

  • Read a number of seconds.
  • Print the whole hours, minutes and seconds, separated by colons.

Input

One whole number.

Output

H:M:S, with no leading zeros.

Constraints

The number is from 0 to 1000000.

Example

Input:

3661

Output:

1:1:1

Why it works

Integer division gives the whole hours, and the remainder is what is left to share into minutes and seconds.

Examples

Example 1 · Input
3661
Expected output
1:1:1
Example 2 · Input
59
Expected output
0:0:59

Hints

Hint 1

There are 3600 seconds in an hour.

Hint 2

% 3600 gives what is left after the whole hours.

Solution

Show one correct solution (try it yourself first)
#include <stdio.h>

int main(void) {
    int total;
    scanf("%d", &total);
    int h = total / 3600;
    int m = (total % 3600) / 60;
    int s = total % 60;
    printf("%d:%d:%d\n", h, m, s);
    return 0;
}
