What are the benefits of memoization in programming?

Memoization is a technique that stores the results of expensive function calls and returns the cached result when the same inputs occur again. This can significantly improve performance, especially in recursive algorithms.

Can you give me an example of where memoization is useful?

Sure! A classic example is the Fibonacci sequence. Without memoization, calculating Fibonacci numbers can lead to a lot of redundant calculations. With memoization, you store previously calculated Fibonacci numbers, which speeds up the process.

Are there any downsides to using memoization?

Yes, while memoization can improve performance, it also uses additional memory to store the cached results. If the input space is large, it can lead to high memory consumption.

How does memoization compare to other optimization techniques?

Memoization is a specific form of caching. Unlike other optimization techniques that may involve algorithmic changes, memoization focuses on storing results of function calls to avoid redundant computations.
