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.io.*;

class Main{
  public static void main(String[] args) {

    InputStreamReader sr = new InputStreamReader(System.in);
    BufferedReader br = new BufferedReader(sr);
    try{
      String str = br.readLine();
      int a = Integer.parseInt(str);
      int h = a / 3600;
      int m = a % 3600 / 60;
      int s = a % 3600 % 60;

      System.out.println(h+":"+m+":"+s);
    }
    catch(IOException e) {
            e.printStackTrace();
    }
  }
}
