Analyze problem approach

Prompt

Analyze the approach for this LeetCode problem without giving the full solution. Explain the problem, possible methods, time and space complexity, and then provide step-by-step hints: Two Sum

Expected

Returns a problem breakdown, multiple solution approaches, complexity comparisons, and gradual hints without revealing full code.

Optimize an existing solution

Prompt

Here is my approach for Longest Substring Without Repeating Characters. Identify performance bottlenecks and suggest better optimization directions without directly rewriting the final answer: <paste my idea or code>

Expected

Returns bottleneck analysis, improvement areas, recommended optimization strategies, and why the complexity becomes better.

Interview prep problem coaching

Prompt

I’m preparing for coding interviews. For Binary Tree Level Order Traversal, guide me like an interviewer: ask for the key idea first, then give hints based on my response, and summarize the core concepts tested.

Expected

Returns interview-style guidance, staged hints, and a summary of the data structures and algorithm concepts being tested.
