What are some common mistakes people make with memoization?

Some common mistakes include not using memoization for all recursive calls, or forgetting to clear the cache.

Can you explain why not using it for all calls is a mistake?

Sure! If you only memoize some calls, you might still end up recalculating results that could have been cached, leading to inefficiency.

What about cache size? Is that a concern?

Yes, cache size can be a concern. If the cache grows too large, it can lead to increased memory usage and potential slowdowns.

How can I manage cache size effectively?

You can implement cache eviction strategies, like LRU (Least Recently Used), to keep the cache size manageable.
