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” is “0”.
- Initialize the variable “exp” is “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 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 “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.
- Check the value of “y”
- Call the “main()” function.

- Exponent y Catherine Arellano mplement a recursive function that returns he exponent given the base and the result. for example, if the base is 2 and the result is 3, then the output should be 3 because the exponent needed for 2 to become 8 is 3 (i.e. 23 = 8) nstructions: 1. In the code editor, you are provided with a main() function that asks the user for two integer inputs: 1. The first integer is the base 2. The second integer is the result 2. Furthermore, you are provided with the getExponent() function. The details of this function are the following: 1. Return type - int 2. Name - getExponent 3. Parameters 1. int - base 2. int - result 4. Description - this recursive function returns the exponent 5.

Write a recursive function GCD that returns the greatest common divisor of x and y. The GCD of x and y is defined as follows: If y is equal to zero, then GCD(x, y) is x; otherwise GCD(x, y) is GCD(y, x % y) where % is the remainder operator.arrow_forward

- PythonDesign a recursive function that accepts an integer argument, n, and prints the number 1 up through n.arrow_forwardProblem Statement for Recursive Sum of Numbers Program Here is a simple recursive problem: Design a function that accepts a positive integer >= 1 and returns the sum of all the integers from 1 up to the number passed as an argument. For example, if 10 is passed as an argument, the function will return 55. Use recursion to calculate the sum. Write a second function which asks the user for the integer and displays the result of calling the function. Part 1. Understand the Problem To design a recursive function, you need to determine at least one base case (the base case returns a solution) and a general case (the general case calls the function again but passes a smaller version of the data as a parameter). To make this problem recursive think about it like this: If the integer is 1, the function will return 1. If the integer is 2, the function will return 1 + 2 = 3. If the integer is 3, the function will return 1 + 2 + 3 = 6. . . . For this problem, we will be sending in the "last"…arrow_forwardRecursive Power MethodWrite a method called powCal that uses recursion to raise a number to a power. The method should accept two arguments: The first argument is the exponent and the second argument is the number to be raised (example” powCal(10,2) means 210). Assume that the exponent is a nonnegative integer. Demonstrate the method in a program called Recursive (This means that you need to write a program that has at least two methods: main and powCal. The powCal method is where you implement the requirements above and the main method is where you make a method call to demonstrate how your powCal method work).arrow_forward
