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;
class Ma {
    
public static void Main(string[] args) {
    
   var n = int.Parse(Console.ReadLine());
   
   int a = 0, h = 0, m = 0 , s = 0;
   h = n / 3600;//h
   a = n % 3600; 
   m = a / 60;//m
   s = a % 60;//
    
 Console.WriteLine("{0}:{1}:{2}", h, m, s); // 文字や数値の出力   
    
}
