2. Optimal Meeting Slots Problem Description: You need to implement a meeting scheduler that uses the schedules of the employees to find a specific number of optimal meeting slots where the largest number of employees can attend. Input: 1. An integer num_slots representing the total of number of meeting slots to return 2. A list of lists of strings representing each employee's list of meetings (parameter employee schedules). Meetings are specified as strings in the format "XX:XX-YY:YY" with XX:XX as the beginning time of the meeting and YY:YY as the end time of the meeting, all in zero-padded 24-hour time (ie 08:30 = 8:30am, 13:00= 1:00pm). The very end of the day can be expressed as 24:00 for simplicity. Example Input: 3 [ M ["00:00-05:30"], ["00:00-05:00", "08:00-22:00"], ["00:00-12:30"]
