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

Solution in JavaScript (judge verdict: Accepted)

(stdin => {
  // Define Function
  // const cube = n => Math.pow(n, 2)
  // Declare Variable
  const inputs = stdin.toString().trim().split('\n')
  const x = parseInt(inputs[0], 10)
  const time =parseInt(x/(60*60))
  const hun= parseInt((x%3600)/60)
  const byo=parseInt(x%60)
  


  console.log(`${time}:${hun}:${byo}`)


 
})(require('fs').readFileSync('/dev/stdin', 'utf8'))
