BFind the minimum number of meeting rooms required for intervals

CFind the maximum number of non-overlapping intervals from a list

DMerge a list of unsorted intervals into non-overlapping intervals

Step-by-Step Solution

Solution:

Step 1: Analyze problem types
Insert interval pattern handles insertion and merging but not resource allocation problems.
Step 2: Identify problem mismatch
Minimum meeting rooms problem requires interval partitioning, not insertion or merging.
Final Answer:
Option B -> Option B
Quick Check:
Meeting rooms problem needs a different approach than insert interval [OK]

Quick Trick: Meeting rooms problem is interval partitioning, not insertion [OK]
