WebA recursive definition of a function defines values of the function for some inputs in terms of the values of the same function for other (usually smaller) inputs. For example, the … WebA proper recursive function must always have a base case : The base case is a way to return without making a recursive call. In other words, it is the mechanism that stops this process of ever more recursive calls and an ever growing stack of function calls waiting on the return of other function calls.
