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 Ruby (judge verdict: Accepted)

class Time
 
  # 1???????§???¨?¨?
  MINUTE_SECOND = 60
 
  #1??????????§???¨?¨?
  HOUR_SECOND = 3600
 
  def initialize(second)
    self.convertTimeFromSecond(second)
  end
 
  # ?§???°????????????????§?????????????????????£????????????????´?????????????
  def convertTimeFromSecond(second)
 
    # ?????????????§??????????????¨????????????????????????????
    @hour = second / HOUR_SECOND
    surplus = second % HOUR_SECOND
 
    # ????¨??????????????????????????¨????????????????????????????
    @minute = surplus / MINUTE_SECOND
    surplus = surplus % MINUTE_SECOND
 
    # ????¨?????????????????§?????¨????
    @second = surplus
  end
 
  def getHour()
    return @hour
  end
 
  def getMinute()
    return @minute
  end
 
  def getSecond()
    return @second
  end
 
end
 
timeInstance = Time.new(gets.chomp.to_i)
puts timeInstance.getHour.to_s + ":" + timeInstance.getMinute.to_s + ":" + timeInstance.getSecond.to_s
