Watch

Write a program which reads an integer $S$ [second] and converts it to $h:m:s$ where $h$, $m$, $s$ denote hours, minutes (less than 60) and seconds (less than 60) respectively.

Input

An integer $S$ is given in a line.

Output

Print $h$, $m$ and $s$ separated by ':'. You do not need to put '0' for a value, which consists of a digit.

Constraints

$0 \leq S \leq 86400$

Solution in Python3 (judge verdict: Accepted)

import sys
def main():
  for line in sys.stdin:
    time = int(line)
    hour = int(time/3600)
    min = int((time - hour * 3600)/60)
    sec = int((time - hour * 3600 - min * 60))
    print("{0}:{1}:{2}".format(hour, min, sec)) 

if __name__ == "__main__":
  main()
