Question

Which of the following statements is false about recursion?

(a) Every recursive function must have a base case

(b) Infinite recursion can occur if the base case isn’t properly mentioned

(c) A recursive function makes the code easier to understand

(d) Every recursive function must have a return value

This question was posed to me in quiz.

This is a very interesting question from Recursion in section Argument Passing, Global vs Local Variables, Shallow copy vs Deep copy and Recursion of Python

Answer 1

Correct choice is (d) Every recursive function must have a return value

Best explanation: A recursive function needn’t have a return value.
