#include<iostream>
using namespace std;
int main(){
	int S;
	cin >> S;
	cout << S/3600 <<":"<<S/60-S/3600*60<<":"<<S%3600%60<< endl;
	return 0;
}
### Prompt

Develop a solution in Cpp to the problem described below:

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.

Constraints

* $0 \leq S \leq 86400$

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.

Example

Input

46979


Output

13:2:59

### Response

#include<iostream>
using namespace std;
int main(){
	int S;
	cin >> S;
	cout << S/3600 <<":"<<S/60-S/3600*60<<":"<<S%3600%60<< endl;
	return 0;
}
