- 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_forwardRecursion is an approach in which the solution to a particular problem depends on solutions to same size instances of the same problem.

- 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_forwardRecursive Power FunctionWrite a function that uses recursion to raise a number to a power. The function should accept two arguments: the number to be raised and the exponent. Assume that the exponent is a nonnegative integer. Demonstrate the function in a program.

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. Thanks in advancearrow_forward
- Recursive Multiplication Design a recursive function that accepts two arguments into the parameters x and y. The function should return the value of x times y. Remember, multiplication can be performed as repeated addition as follows: 7×4=4+4+4+4+4+4+4(To keep the function simple, assume that x and y will always hold positive nonzero integers.)arrow_forwardRecursion is the best and the fastest way to solve any problem.True or Falsearrow_forward2.
