Each of the programs in Figure 9-25 uses a recursive method. Try to determine the output in each case.

a. b. c. start start start output recursiveA(0) stop num recursiveA(num x) num result if x = 0 then result = x else result = x output recursiveB(2) stop num recursiveB (num x) num result if x = 0 then result = x else result = x output recursiveC(2) stop num recursiveC(num x) num result if x = 1 then result = x else result = x (recursiveA(x - 1)) (recursiveB(x - 1)) (recursivec(x - 1)) endif return result endif return result endif return result Figure 9-25 Problems for Exercise 15
