#include <stdio.h>
  
int main(){
  
int S,h,m,s;
  
scanf("%d",&S);

m=S/60;
h=m/60;
s=S%60;
m=m%60;
  

  
printf("%d:%d:%d\n",h,m,s);
  
  
}
### Prompt

Your task is to create a Cpp solution to the following problem:

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 <stdio.h>
  
int main(){
  
int S,h,m,s;
  
scanf("%d",&S);

m=S/60;
h=m/60;
s=S%60;
m=m%60;
  

  
printf("%d:%d:%d\n",h,m,s);
  
  
}
```
