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 Ruby (judge verdict: Wrong Answer)



s = STDIN.gets.to_i
# s = 46979
#p s

# "13:2:59"


H = 60*60
M = 60
p h = s/H
p m = (s - H*h) / M
p s = (s - H*h - m*M)



puts "#{h}:#{m}:#{s}"
