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 = input()
S = int(S)

h = (S - (S%3600)) / 3600
m = (S%3600 - (S%3600)%60) / 60
s = S-((3600*h)+(60*m))

print('%d:%d:%d'%(h,m,s))
