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

$0 \leq S \leq 86400$

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

class Main {
  public static void main(String args[]) {
	  	Scanner scanner = new Scanner(System.in);
	  	int  num = scanner.nextInt();
	  	int  a = num/3600;
	  	int R = num%3600;
	  	int  b = R/60;
	  	R = R%60;
	  	int c = R%60;
        System.out.print(a +"："+ b + "：" + c);
        scanner.close();
  }
}
