WebNov 27, 2024 · Finding the recursive steps. The Base Case. Recursion can be seen as a reduction from the bigger problem to the simplest, smallest instance of the same problem. The smallest of all sub-problems is called the base case. This is what we should find first. In the real world, your recursive process will often take the shape of a function. WebHere is a general pattern for transforming an almost tail-recursive function into a loop: Define an accumulator variable and initialize it with the base case value. Define a loop with a condition that checks if the base case has been reached. Inside the loop, perform the computation that was previously done after the recursive call using the ...
