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

$0 \leq S \leq 86400$

Solution in Scala (judge verdict: Accepted)


object Main{
 def main(args:Array[String]):Unit ={
  val S = readInt
  val s = S%60
  val m = (S - s)/60%60
  val h = ((S - s) - m*60)/(60*60)
  println(s"$h:$m:$s")
 }
}
