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.

14 T OR F Recursive methods are always shorter and clearer than the equivalent nonrecursive methods.

what is a recursive solution to a problem?

T/F 1. Infinite recursion occurs where a recursive form lacks a base case.

bottom up recursive solution to 1 + 2 + 3 +...+ n please show work step by step (dyanamic programming) on paper/ typed

What is the functionality of base case(s) ? Group of answer choices: Call other base cases Make recursive function call Checks the logical error To complete the recursion What is the functionality of base case(s) ? Group of answer choices: Call other base cases Make recursive function call Checks the logical error To complete the recursion What is the functionality of recursive helper method ? Group of answer choices: Define base cases and recursive cases Extends the original recursive method Makes infinite function calls Make function calls to original recursive method A recursion function can be implemented without pending operations. Group of answer choices: True False

CS211 Non-recursive solution for Towers of Hanoi Using the algorithm discussed in class, write an iterative program to solve the Towers of Hanoi problem. The problem: You are given three towers a, b, and c. We start with n rings on tower a and we need to transfer them to tower b subject to the following restrictions: 1. We can only move one ring at a time, and 2. We may never put a larger numbered ring on top of a smaller numbered one. There are always 3 towers. Your program will prompt the user for the number of rings. Here is the algorithm. Definition: A ring is "available" if it is on the top of one of the towers. Definition: The "candidate" is the smallest available ring that has not been moved on the most recent move. The first candidate is ring 1. The Algorithm: 1. Find the candidate. 2. Move the candidate (right or left, depending if the number of rings is odd or even) to the closest tower on which it can be placed. Move "around the circle" if necessary. 3. If not done, go back...

Backtracking normally uses ______ to find out all solutions to a computational problem. (recursion, iteration).

Palindrome should have a recursive definition.

Consider the following sequence and answer the questions 3, 12, 27, 48, 75, . (1) Develop the recursive solution to identify numbers in the list. (2) Develop the closed-form solution of the recursive solution you made in the previous question.

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

T/F 11. A recursion will still be replaced by an iteration and the other way around.

When recursion is used to solve a problem, why must the recursive method call itself to solve a smaller version of the original problem?
