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

Sample Output 1

Solution in Python3 (judge verdict: Accepted)

S = int(input())
if 0 <= S and S <= 86400 :
    h = (S - (S % 3600)) // 3600
    m = (((S % 3600) - ((S % 3600) % 60)) // 60)
    s = ((S % 3600) % 60)
    print(str(h) + ":" + str(m) + ":" + str(s))
