Problem:
MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

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

$0 \leq S \leq 86400$

Sample Input 1

46979

Sample Output 1

13:2:59

Solution in Scala (judge verdict: Accepted)

import scala.io.StdIn

object Main extends App {
  val s = StdIn.readLine().trim.toInt
  val basemin   = 60
  val basehour  = 60 * 60

  val rs = s % 60
  var temp = s - rs
  val rh = temp / basehour

  temp = temp - basehour * rh

  val rm = temp / basemin

  println(s"$rh:$rm:$rs")
}
