Recursion involves a function calling itself to solve a problem from "summary" of Data Structures and Algorithms in Python by Michael T. Goodrich,Roberto Tamassia,Michael H. Goldwasser
Recursion is a powerful technique in programming where a function calls itself to solve a problem. This process involves breaking down the main problem into smaller subproblems that can be solved in a similar manner. Each recursive call works on a smaller subset of the original problem until a base case is reached, at which point the function stops calling itself and begins to return values back up the call chain. When implementing recursion, it is crucial to have a clear understanding of the base case, which defines the simplest version of the problem that does not require further recursive calls. Without a base case, the recursive function would continue to call itself indefinitely, leading to a stack overflow error. An important aspect o...
