All recursive solutions are efficient and practical. True False QUESTION 2 Which of the following it true of a recursive solution? All of these A recursive function calls itself. Each recursive call solves an identical but smaller problem. A test for the base case enables the recursive calls to stop. Eventually, one of the smaller problems must be the base case. QUESTION 3 Many problems that are not easily solved with iterating end up having relatively simple recursive solutions. True False QUESTION 4 Recursion breaks a problem into smaller identical problems. True False
