You're given a function that calculates Fibonacci numbers recursively with memoization, but profiling shows it's still slow for n 10,000. Identify the bottleneck and propose two different optimizations.

Question

You're given a function that calculates Fibonacci numbers recursively with memoization, but profiling shows it's still slow for n > 10,000. Identify the bottleneck and propose two different optimizations.

Answer

Stay specific. One example, told well, beats three told fast. Make your decisions visible — what you chose between. End on what changed, for whom.
