Hoare partition scheme, in-place.
Pick a pivot, partition so smaller elements are on the left, then recurse.
Mitigation: randomized pivot or median-of-three.

How It Works
Hit record during algorithms, data structures, or systems lectures. ThetaWave captures code, pseudocode, and verbal explanations together.
Notes connect the algorithm explanation to its pseudocode, time complexity, and use cases — not isolated snippets.
Flashcards for Big-O, data structures, design patterns, and key algorithms — ready for exams and interviews.
Your professor writes code while explaining the logic. You either copy the code or listen to the explanation — you can't do both.
You understood Dijkstra's during class. At midnight debugging your assignment, the intuition is gone and your notes say 'shortest path - use priority queue.' AI notes capture the full explanation.
Big-O analysis in your notes, implementation in your IDE, and the professor's explanation in your memory.
Record lectures where the professor codes live. Get the code, the verbal explanation, and the complexity analysis in one structured document.
Upload lecture recordings and slides. Get notes that connect algorithm explanations to pseudocode, time/space complexity, and real-world applications.
Auto-generate cards for sorting algorithms, graph traversals, dynamic programming patterns, and data structure operations — exam and interview ready.
These examples are closer to what students actually keep and review after class, meetings, or exam prep.

| Feature | ThetaWave | ChatGPT |
|---|---|---|
| Handling real course material | Lectures, PDFs, meetings, and readings for For CS Students stay in one workflow | Usually handled one request at a time |
| What gets organized | Notes, follow-ups, key points, and next actions stay together | You still have to restructure the output yourself |
| What you can reuse later | Built to support review, writing, meetings, and longer projects | Good for one-off answers, weaker for ongoing study workflows |
| Grounding | Anchored to your own material | More dependent on generic generation |
| Fit for this workflow |
