BattleExam shows you the one core pattern each exam topic tests — then drills it with infinite fresh questions until you own it.
Live practice session
Core pattern
Divide-and-conquer recurrence: cost = 2 sub-problems of n/2 + linear merge.
What is the recurrence relation for Merge Sort on n elements?
✓ Correct — here's why
Merge Sort splits into 2 sub-problems of size n/2 (→ 2T(n/2)) and merges in O(n), giving O(n log n) overall by Master Theorem.
How it works
Generated questions at your level. Each tagged to a pattern — not just a topic.
Instant explanation, reasoning steps, and links to the short-note for the pattern.
Next session focuses on the patterns you're weakest on. Drill until mastered.
