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

Solution in C# (judge verdict: Accepted)

using System;

namespace ConsoleApp7
{
    class Program
    {
        public const int HOUR = 3600;
        public const int MIN = 60;

        static void Main(string[] args)
        {
            int NUM = int.Parse(Console.ReadLine());
            int H = NUM / 3600;
            int ret = NUM % 3600;
            int M = ret / 60;
            int S = ret % 60;
            Console.WriteLine("{0}:{1}:{2}", H, M, S);
        }
    }
}
