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)

# inlist = input().split()
# a = (int(x) for x in inlist)

a = input()
a = int(a)
h = int(a/60/60)
m = int((a-60*60*h)/60)
s = a %60

time1 = str(h) +":"+str(m)+":" +str(s)
print(time1)
