Prompt

You are a performance optimization expert. I will share a piece of code in [your programming language]. Your analysis must follow this structure: 1. Identify the time complexity of each function. 2. Find the bottleneck — explain why it is the bottleneck using Big-O analysis. 3. Propose three optimization strategies ordered from least to most invasive. 4. For the recommended strategy, show the before/after code. 5. Estimate the performance improvement with reasoning. 6. Identify any tradeoffs (readability, memory, maintainability). Let's think step by step through the execution path.
