1904 - The Number of Full Rounds You Have Played\. Medium You are participating in an online chess tournament. There is a chess round that starts every `15` minutes. The first round of the day starts at `00:00`, and after every `15` minutes, a new round starts. * For example, the second round starts at `00:15`, the fourth round starts at `00:45`, and the seventh round starts at `01:30`. You are given two strings `loginTime` and `logoutTime` where: * `loginTime` is the time you will login to the game, and * `logoutTime` is the time you will logout from the game. If `logoutTime` is **earlier** than `loginTime`, this means you have played from `loginTime` to midnight and from midnight to `logoutTime`. Return _the number of full chess rounds you have played in the tournament_. **Note:** All the given times follow the 24-hour clock. That means the first round of the day starts at `00:00` and the last round of the day starts at `23:45`. **Example 1:** **Input:** loginTime = "09:31", logoutTime = "10:14" **Output:** 1 **Explanation:** You played one full round from 09:45 to 10:00. You did not play the full round from 09:30 to 09:45 because you logged in at 09:31 after it began. You did not play the full round from 10:00 to 10:15 because you logged out at 10:14 before it ended. **Example 2:** **Input:** loginTime = "21:30", logoutTime = "03:00" **Output:** 22 **Explanation:** You played 10 full rounds from 21:30 to 00:00 and 12 full rounds from 00:00 to 03:00. 10 + 12 = 22. **Constraints:** * `loginTime` and `logoutTime` are in the format `hh:mm`. * `00 <= hh <= 23` * `00 <= mm <= 59` * `loginTime` and `logoutTime` are not equal.
