Problem Statement

I woke up, but since it is the season for going back to sleep, I am thinking of sleeping for another 5 minutes.
Given the time of the first wake-up, find the time 5 minutes later.

Input

T

$T$ is given in the format $hh:mm$.
It satisfies $0 \le hh \le 23$, and values with $0 \le hh \le 9$ are written with two digits by prepending a $0$.
It satisfies $0 \le mm \le 59$, and values with $0 \le mm \le 9$ are written with two digits by prepending a $0$.
Therefore, $00:00 \le T \le 23:59$ holds. There is a newline at the end of the input file.

Output

Output the time $5$ minutes after $T$ in the format $hh:mm$. Print a newline at the end.
