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: Time Limit Exceeded)

#include<stdio.h>
int main(){
	int a,b,c,d,e,f,g[500];
	scanf("%d",&a);
	if(a>3600){
	b=a/3600;
	}else{b=0;}
	if(a>60){
	}else{c=0;}
	c=a/60;
	while(1){
		if(a>=60){
			a-=60;
		}
		if(a<60){
			break;
		}
	}
	//		printf("OK");
		while(1){
		if(c>60){
			c-=60;
		}
		if(c<60){
			break;
		}
	}

	printf("%d:%d:%d\n",b,c,a);
	
	return 0;
