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

Solution in Scala (judge verdict: Accepted)

object Main {
	def main(args:Array[String]) = {
		val in = readInt
		val hour = (in / 3600) % 24
		val minute = (in / 60) % 60
		val second = in % 60
		println(hour + ":" + minute + ":" + second)
	}
}
