Question
What will be the output of the following pseudocode for a = 4, b = 6?Integer funn(Integer a, Integer b) If(a > 1) Return a * funn (b - 6, a - 4) Else Return 1 End If Return a + b End function funn()Question 79AnswerA.7B.17C.4D.0
Solution
The pseudocode provided is a recursive function. Here's how it works:
- The function
funnis called witha = 4andb = 6. - The
ifcondition checks ifa > 1. Sincea = 4, the condition is true. - The function then returns
a * funn(b - 6, a - 4). This means it will return4 * funn(0, 0). - Now, the function
funnis called again witha = 0andb = 0. - The
ifcondition checks ifa > 1. Sincea = 0, the condition is false. - The function then returns
1. - Going back to step 3, the function now returns
4 * 1 = 4.
So, the output of the pseudocode for a = 4 and b = 6 is 4. Therefore, the correct answer is C. 4.
