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

Solution in Scala (judge verdict: Wrong Answer)

object Main {
   def main (args: Array[String]) {
     val input:Int = scala.io.StdIn.readInt();
     val hour:Int  = input/(60*60)
     val min:Int   = (input / 60 * 60) % 60
     val sec:Int   = input % 60
     println( hour + ":" + min + ":" + sec );
  }
}
