Consider the binary search approach for minimum interval queries. Given intervals = [[5,5]] and queries = [5], what is the output?
Consider the binary search approach for minimum interval queries. Given intervals = [[5,5]] and queries = [5], what is the output?
medium🧾 Code Trace Q4 of Q15
Step-by-Step Solution
Solution:
Step 1: Calculate interval length
Interval [5,5] length is 1.Step 2: Binary search for minimal length covering query 5
Check length=1: covers returns True since 5 is within [5,5]. So answer is 1.Final Answer:
Option D -> Option DQuick Check:
Single interval covers query exactly with length 1 [OK]
Quick Trick: Minimal interval length equals 1 for single-point intervals [OK]
Common Mistakes:
MISTAKES- Confusing length calculation or binary search boundaries
Trap Explanation:
PITFALL- Candidates may think length 0 or query not covered due to off-by-one errors in length calculation.
Interviewer Note:
CONTEXT- Tests boundary conditions and binary search correctness on minimal intervals
