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 C# (judge verdict: Accepted)

using System;

namespace Watch{
	 class class1{
		 static void Main(){
			int S=int.Parse(Console.ReadLine());
			Console.Write("{0}:{1}:{2}\n",h(S),m(S),s(S));
		}

		 static int s(int S){return S%3600%60;}
		 static int m(int S){return S%3600/60;}
		 static int h(int S){return S/3600;}	
		
	}
}
