#include<bits/stdc++.h>
using namespace std;

int main(){
  int s;
  cin>>s;
  
  cout<<s/3600<<":"<<(s%3600)/60<<":"<<s%60<<endl;

  return 0;
}
### Prompt

Construct a cpp code solution to the problem outlined:

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<bits/stdc++.h>
using namespace std;

int main(){
  int s;
  cin>>s;
  
  cout<<s/3600<<":"<<(s%3600)/60<<":"<<s%60<<endl;

  return 0;
}
