Let's learn what memoization is, why you might use it, and how do we write it from scratch. Memoization is a technique that enhances a function by creating and using a cache to store and retrieve results of that function. Memoization uses the arguments of a function to create a key for the cache. The first time a memoized …

NettetMemoization is an optimization technique used to speed up processes by storing the results of function calls and returning such cached results when its input is required. As one can tell, memoization can work very nicely with recursive algorithms to greatly improve efficiency.
