Which of the following problems CANNOT be solved correctly using the merge intervals pattern (sorting + merging overlapping intervals)?
easy🔍 Pattern Recognition Q2 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand the merge intervals pattern
This pattern merges overlapping intervals into consolidated intervals, suitable for combining booked times or ranges.Step 2: Analyze each option
Combine overlapping booked meeting times into consolidated slots, B, and C relate to merging or scheduling intervals. However, Combine overlapping intervals representing video playback segments involves combining video playback segments which may require handling partial overlaps with additional metadata, not just merging intervals.Final Answer:
Option B -> Option BQuick Check:
Video playback segments often need more than simple interval merging [OK]
Quick Trick: Interval scheduling (max non-overlapping) ≠ merge intervals [OK]
Common Mistakes:
MISTAKES- Confusing interval scheduling with merging
- Assuming all interval problems use merge pattern
Trap Explanation:
PITFALL- Candidates often think all interval problems can be solved by merging, but some require different approaches like scheduling or segment trees.
Interviewer Note:
CONTEXT- Tests anti-pattern recognition and understanding of problem nuances.
