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)

var readable = process.stdin;
readable.resume();
readable.setEncoding( 'utf-8' );
readable.on( 'data', function( chunk ) {
  var data = parseInt( chunk );
  var h = Math.floor( data/3600 );
  data = data%3600;
  var m = Math.floor( data/60 );
  var s = Math.floor( data%60 );  
  console.log( h+':'+m+':'+s );
} )
