MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

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 JAVA (judge verdict: Accepted)

import java.util.*;
public class Main {
   public static void main(String args[]){
      //declaration and initialization
      Scanner sc = new Scanner(System.in);
      String input[];
      
      //reading the intput
      input = sc.nextLine().split(" ",0);
      
      //variables for each problem
      int time;
      int hour;
      int min;
      int sec;
      
      //assginment
      time = Integer.parseInt(input[0]);
            
      //calculation
      
      hour = time/3600;
      time -= hour * 3600;
      
      min = time/60;
      sec = time%60;
                  
     //output
      System.out.println(hour + ":" + min + ":" + sec);
      
      
      
   }//main
