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 C# (judge verdict: Accepted)

using System;
public class Hello{
    public static void Main(){
        string[] i = Console.ReadLine().Split();
       int a = int.Parse(i[0]);
       int b = a/3600;
       int c = a%3600;
       int d = c/60;
       int e = c%60;
   
     Console.WriteLine(b+":"+d+":"+e);
    }
}
