The following recursion occurs when there are more than two calls for each non-base case: :
c)Multiple recursion
d)Two Step Recursion
a)Linear recursion
b)Binary recursion
Simple answer.
Choose a or b or c or d.
Recursion is an approach in which the solution to a particular problem depends on solutions
to same size instances of the same problem.
Select one:
O True
O False

- Let S be the set of positive integers defined by: Basis step: 4 € S. Recursive step: If nE S, then 5n +2 e S and n? e S. (a) Find four elements of S that are less than 120. (b) What is the remainder of each of the four elements of S you listed above when they are each divided by 6. Note: You should get the same number. Show the math for each number. (c) State a hypothesis about the remainder of any element of S when the element is divided by 6. Explain how you would use structural induction over the set S to prove your hypothesis. Note: You do not need to actually prove your hypothesis, but clearly explain the steps you would take including the basis step and the inductive step.arrow_forwardAlgorithm problem w/ recurrence: Frying pancakes: a small pan can only hold two pancakes at a time. Each pancake needs to be fried on both sides. Frying one side takes 1 minute, no matter how many pancakes are on the pan. Consider this recursive algorithm: If n <= 2, fry the pancakes or the two pancakes together on each side. If n > 2, fry any two pancakes together on each side and then apply the same process recursively to the remaining n-2 pancakes. a. Set up and solve the recurrence for the amount of time this algorithm needs to fry n pancakes. b. Explain why this algorithm does not fry the pancakes in the minimum time for all n > 0. c. Give a correct recursive algorithm that executes the task in the minimum amount of time. > I was not sure how to start this. I have had trouble with recurrence in the past. Also from the work that I did do, I didn't know how there could be a better algorithm.

- Is the recursive solution to the triangle number the best way to obtain the triangle number? A. Yes, because recursive solutions are always efficient. B. Yes, because the shape of the triangle number diagram lends itself to a recursive solution. C. No, the triangle number can be found in a more efficient manner. D. None of the above are true.arrow_forward2.
