Problem M
A Second Opinion

Write a program that, given a duration in seconds as input, outputs the same duration as hours, minutes, and seconds.

Hint: use integer division (//) and remainder (%).

Input

One line containing the integer $s$, the number of seconds that should be rewritten, where $0\le s\le 1000000$.

Output

One line containing three integers, the number of hours, the number of minutes, and the number of seconds separated by a space, a colon, and another space.

1000

0 : 16 : 40

80000

22 : 13 : 20
