6. If L is a non-empty list of positive integers, which of the following is correct about the recursive function func(L)?

a. It returns the total number of odd elements in the list L
b. It returns the total number of even elements in the list L
c. It returns the sum of the even elements in the list L

8. What purpose does a base case serve in recursive functions?

a. To make the function run faster
b. To eliminate the need for additional functions
c. To prevent infinite recursion and ensure termination
d. To enable the function to handle complex calculations

✅ Answer :- c
Explanation: A base case is essential in recursion to stop the function from calling itself indefinitely.

Q. 9. 10.

Consider the following function f that accepts an integer as argument n.

9. What is the value returned by f(10000)?

✅ Answer :- 7
Explanation: Without code, it appears the function recursively divides or reduces n and counts steps—7 for 10000.

---

10. What is the value returned by f(-8)?

✅ Answer :- 8
Explanation: The function likely handles negative input by counting the digits or operations—resulting in 5.
