Problem:
MathJax.Hub.Config({ tex2jax: { inlineMath: [["$","$"], ["\\(","\\)"]], processEscapes: true }});

Watch

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.

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.

Constraints

$0 \leq S \leq 86400$

Sample Input 1

46979

Sample Output 1

13:2:59

Solution in JavaScript (judge verdict: Wrong Answer)

'use strict';
process.stdin.on('data', function(chunk) {
  var inputs = chunk.toString().trim();
var S = Number(inputs);
var h = Math.floor(S/3600);
var m = h % 60;
var s = S % 60;

 console.log([h,m,s].join (':'));
});
process.stdin.resume();
process.stdin.setEncoding('utf8');
