Solving LeetCode 2402: Meeting Rooms III.
This hard problem combines priority queues + simulation, where meetings must be scheduled fairly while tracking which room gets used the most 🏢⏱️

The Logic (Two Priority Queues):
Sort all meetings by their start time.
Maintain a min-heap of free rooms (by room number).
Maintain a min-heap of busy rooms ordered by earliest finishing time (and room number).
For each meeting:
Free up rooms whose meetings have ended.
If a room is free, assign the meeting immediately.
Otherwise, delay the meeting until the earliest room becomes free.
Count how many meetings each room handles.
Return the room with the maximum meetings (smallest index if tied).
This simulation guarantees correct scheduling while respecting all constraints.

Complexity:
Time: O(M log N)
Space: O(N)
