Question 5 When writing a recursive method, O you do not need to know ahead of time exactly how many levels of recursion will occur. O you must keep count of how many recursion call levels you have traversed. O you must make sure the method does not take any input parameters.
T/F 9. As loop variables and recursive solutions are also not used for iterative solutions, the recursive solution generally makes memorization more effective (use fewer stored) than the corresponding iterative solution.
When looking at this code making recursive calls, how would I identify how many recursive calls are being made?
9. Ackermann's Function Ackermann's function is a recursive mathematical algorithm that can be used to test how well a computer performs recursion. Write a method ackermann (m, n), which solves Ackermann's function. Use the following logic in your method: If m = 0 then return n + 1 If n = 0 then return ackermann (m Otherwise, return ackermann(m 1, 1) 1, ackermann (m, n - 1))

For function sumtok, write the missing recursive call. This function returns the sum of the values from 1 to k. Examples: sumtok(5) -> 15 public int sumtok(int k) { if (k <= 0) { return 0; } else { return <<Missing Recursive case action>> }}
Write the output of the following recursive code snippet. void exam_recursive_function (int x) If (x == 0) Return printf ("%d", x) exam_recursive_function (x-2) int main () exam_recursive_function (20) return 0 (a) 20 19 18 17 16 15 14 13 12 11 10 9 876543210 (b) 18 17 16 15 14 13 12 11 10 9 876543210 (c) 20 18 16 14 12 10 8642 (d) 2 468 10 12 14 16 18 20
Why does dynamic programming provide faster solutions that recursive algorithms solving the same problem? 1.avoids resolving overlapping subproblems 2.dynamic programming uses dynamic memory that is more efficient than stack memory 3.loops are always faster than recursion 4.dynamic uses arrays that are faster than function calls
For function addOdd(n) write the missing recursive call. This function should return the sum of all postive odd numbers less than or equal to n. Examples: addOdd(1) -> 1addOdd(2) -> 1addOdd(3) -> 4addOdd(7) -> 16 public int addOdd(int n) { if (n <= 0) { return 0; } if (n % 2 != 0) { // Odd value return <<Missing a Recursive call>> } else { // Even value return addOdd(n - 1); }}
1. Let product(n,m) be a recursive addition-subtraction method for multiplying two positive integers. Recursive cases for m = 1 and m < 1 make this method. The return value should be n plus a recursive product() call with n and m - 1. Test a Java method.
