- If your first name starts with a letter from A-J inclusively: Create a recursive algorithm to compute the product of two positive integers, m and n, using only addition and subtraction. Implement the Java or Python code. Hint: You need subtraction to count down from m or n and addition to do the arithmetic needed to get the right answer. Check linearSum method from Week 5 examples. If your first name starts with a letter from K-Z inclusively: Write a recursive method to produce the following pattern: * ** *** **** *** ** * Test the method by asking the user to enter the number of asterisks of the maximum line (for example, the user should enter 4 in this case).Algorithm 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. Thanks in advanceWhat does the ff. algorithm return?

- Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. The conventional algorithm for evaluating a polynomial a,c" + an-1 c? - 1 +..+ ajc+ ao at x= c can be expressed in pseudocode by procedure polynomial(c, ao, a1. - .., an real numbers) power:= 1 y:= ao for i:= 1 to n power := power* c y:= y+ aj* power return y{y= anc" + an-1 c" -1+...+ a1c+ ao } where the final value of y is the value of the polynomial at x = c. Find the values of A, B, and C on evaluating 3x2 + x +1 at x= 2 by working through each step of the algorithm and showing the values assigned at each assignment step. power:= 1, y:= 1; i:=1 power:= 2, y := A; i= 2 power:= B, y:= C A B = and C =Use back substitution method to compute the following recursive function. Note that final results must be presented as a function of n. Show at least three substitutions before moving to k steps to get credit.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.
- Write a recursive algorithm with the following prototype: int add (int x, int y); that returns x if y is 0; and adds x to y otherwise. THE FUNCTION MUST BE RECURSIVE. (hint: the base case should involve a test for y being 0; recursive case should reduce y towards 0)The following snippet of pseudocode fails to live up to all of the clarity, correctness, and termination requirements of algorithms. In each case, describe the failing step, and thenrewrite the pseudocode as a proper algorithm. def long_division(numerator, denominator): quotient = numerator/denominator remainder = numerator % denominatorNuts and bolts You are given a collection of n bolts of different widths and n corresponding nuts. You are allowed to try a nut and bolt together, from which you can determine whether the nut is larger than the bolt, smaller than the bolt, or matches the bolt exactly. However, there is no way to compare two nuts together or two bolts together. The problem is to match each bolt to its nut. Design an algorithm for this problem with average-case efficiency in (n log n).
