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

$0 \leq S \leq 86400$

Solution in Python3 (judge verdict: Accepted)

number=input()
number=int(number)

if number>=3600:
    if number>=3660:
        h=number//3600
        m=(number-h*3600)//60
        s=(number-h*3600)-m*60
    else:
        h=number//3600
        m=0
        s=(number-h*3600)
        pass
else:
    if number>=60:
        h=0
        m=number//60
        s=number-m*60
    else:
        h=0
        m=0
        s=number
print(str(h)+":"+str(m)+":"+str(s))
