#include <iostream>
int main(){
int S,h=0,m=0;
std::cin>>S;
h=S/3600;
S=S%3600;
m=S/60;
S=S%60;
std::cout<<h<<":"<<m<<":"<<S<<std::endl;
}
### Prompt

Please provide a Cpp coded solution 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>
int main(){
int S,h=0,m=0;
std::cin>>S;
h=S/3600;
S=S%3600;
m=S/60;
S=S%60;
std::cout<<h<<":"<<m<<":"<<S<<std::endl;
}
```
