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

$0 \leq S \leq 86400$

Solution in Python3 (judge verdict: Wrong Answer)

a = input()
a = int(a)
s = a%60
m = (a-a%60)/60%60
h = (a-s-m*60)/3600
m = int(m)
h = int(h)
s=str(s)
m=str(m)
h=str(h)
print(s + ':'+m+':'+h)
