Program Plan Intro

Recursive Power Method

Program Plan:

• Global variable declaration:

○ Initialize the variable “minimum” as “1”.

○ Initialize the variable “maximum” as “100”.

• Define the “main()” function:

○ Initialize the variable “number” as “0”.

○ Initialize the variable “exp” as “0”.

○ Get the input from the user and store it to the variable “number”.

○ Check the value of “exp”

■ If it is less than “minimum” or greater than “maximum”, then get the exponent “exp” from the user.

○ Call the function “recursivePower()” and pass the two arguments “number” and “exp”.

○ Display the result on the output screen.

• Define the “recursivePower(x, y)” function:

○ Check the value of “y”.

■ If it is equal to “0”, then returns is “1”.

■ Otherwise, call the function “recursivePower()” recursively along with the arguments “x” and the decremented value of “y”.

■ Display the result on the output screen.

• Call the “main()” function.

(Dynamic Programming.) Recall the problem presented in Assign- ment 3 where given a list L of n ordered integers you're tasked with removing m of them such that the distance between the closest two remaining integers is maxi- mized. See Assignment 1 for further clarification and examples. As it turns out there is no (known) greedy algorithm to solve this problem. However, there is a dynamic programming solution. Devise a dynamic programming solution which determines the maximum distance between the closest two points after removing m numbers. Note, it doesn't need to return the resulting list itself. Hint 1: Your sub-problems should be of the form S(i, j), where S(i, j) returns the maximum distance of the closest two numbers when only considering removing j of the first i numbers in L. As an example if L [3, 4, 6, 8, 9, 12, 13, 15], then S(4, 1) = 2, since the closest two values of L' = [3,4,6,8] are 6 and 8 after removing 4 (note, 8-6 = = 2). = Hint 2: For the sub-problem S(i, j),…
