#include <iostream>
using namespace std;

int main () {

 int s;

 cin >> s;
 cout << s/3600 <<':'<< s/60%60 <<':'<< s%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

```cpp
#include <iostream>
using namespace std;

int main () {

 int s;

 cin >> s;
 cout << s/3600 <<':'<< s/60%60 <<':'<< s%60 <<endl;

 return 0;
}
