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)

object Main {
  def main(args: Array[String]) = {
    
    val input: String = readLine()
    val sec: Int = input.toInt

    val devideAndMod = (a: Int, b: Int) => (a / b, a % b)

    var (hour: Int, remainMin: Int) = devideAndMod(sec, 3600)
    var (minute: Int, remainSec: Int) = devideAndMod(remainMin, 60)
    
    println(hour + ":" + minute + ":" + remainSec)
  }  
  
  //def readLine(): String = {"46979"}
}
