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 C# (judge verdict: Accepted)

using System;

class Program
{
  public static void Main(string[] args)
  {
    int seconds = int.Parse(Console.ReadLine());
    int[] times = new int[3];
    int division = 3600;
    for(int i = 0;i < 3;i++)
    {
      times[i] = seconds/division;
      seconds %= division;
      division /= 60;
    }
    Console.WriteLine("{0}:{1}:{2}",times[0],times[1],times[2]);
  }
}
