You are participating in an online game where rounds are played continuously throughout the day. Each round lasts for $15$ minutes and starts at $00$, $15$, $30$, or $45$ minutes past every hour.

You are given two strings loginTime and logoutTime representing your login and logout times in $24$ hour format.

Return the total number of full rounds you played during your gaming session.

If logoutTime is earlier than loginTime, the gaming session started on one day and finished on the following day.

Constraints:

• loginTime and logoutTime are in the format hh:mm.

• $00 \leq$ hh $\leq 23$

• $00 \leq$ mm $\leq 59$

• loginTime and logoutTime are not equal.
