Program Plan Intro
Recursive Multiplication
Program Plan:
- • Define the “main()” function:
- ○ Initializes the variable “n1” as “0”
- ○ Initializes the variable “n2” as “0”
- ○ Check the value of “n1”.
- ■ If it is less than or equal to “0”, then get the first number from the user and store it to the variable “n1”.
- ○ Check the value of “n2”.
- ■ If it is less than or equal to “0”, then get the second number from the user and store it to the variable “n2”.
- ○ Call the function “multiplyRecursive()” and pass the two arguments “n1” and “n2”.
- • Define the “multiplyRecursive()” function:
- ○ Check the value of “x” and “y”
- ■ If it is equal to “0”, then return “0”.
- ■ Otherwise, call the function “multiplyRecursive()” to recursively perform the addition operation.
- ○ Check the value of “x” and “y”
- • Call the “main()” function.

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.)

Drawing a right side up triangle
Write a recursive function called DrawTriangle() that outputs lines of '*' to form a right side up isosceles triangle. Function DrawTriangle() has one parameter, an integer representing the base length of the triangle. Assume the base length is always odd and less than 20. Output 9 spaces before the first '*' on the first line for correct formatting.
Hint: The number of '*' increases by 2 for every line drawn.
Ex: If the input of the program is:
3
the function DrawTriangle() outputs:
* ***
Ex: If the input of the program is:
19
the function DrawTriangle() outputs:
* *** ***** ******* ********* *********** ************* *************** ***************** *******************
Note: No space is output before the first '*' on the last line when the base length is 19. in c++

- Problem 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_forward2. Sum: a recursive function that computes the sum of integers 1, 2, 3, …., n for a given number n. So Sum(6) should return 1 + 2 + 3 + 4 + 5 + 6 , i.e. 21.sum(n) = n + sum(n-1)arrow_forwardPython program (recursive function) A recursive function is a function defined in terms of itself via self-referential expressions. This means that the function will continue to call itself and repeat its behavior until some condition is met to return a result. Write a python recursive functionprod that takes x as an argument, and returns the result where, result=1*1/2*1/3*….*1/n Include a screenshot that shows a python program that uses the above function and prints the rounded result to three decimal placesafter prompting the user to enter a number, x. Use x=3. N.B: The code should be included please.arrow_forward
- (Recursive Greatest Common Divisor) The greatest common divisor of integers x and y isthe largest integer that evenly divides both x and y. Write a recursive function gcd that returns thegreatest common divisor of x and y. The gcd of x and y is defined recursively as follows: If y is equalto 0, then gcd(x, y) is x; otherwise gcd(x, y) is gcd(y, x % y), where % is the remainder operator.arrow_forwardc++ A palindrome is a string that reads the same both forward and backward. For example, the string "madam" is a palindrome. Write a program that uses a recursive function to check whether a string is a palindrome. Your program must contain a value-returning recursive function that returns true if the string is a palindrome and false otherwise. Do not use any global variables; use the appropriate parameter.arrow_forwardPYTHON CS1 PROBLEM (NO LOOPS) Define a recursive function that takes two strings str1 and str2 as parameters. It returns True if str1 is a suffix of str2, otherwise it should return False.For example: If str1 = True. If str1 = False. If str1 = If str1 = If str1 = If str1 = “washer” and str2 = “dishwasher” then your function should return “wash” and str2 = “dishwasher” then your function should return “” and str2 = “test” then your function should return True. “test” and str2 = “” then your function should return False.“” and str2 = “” then your function should return True.“test” and str2 = “test” then your function should return True.arrow_forward

Given a positive integer as input (Ex: 12), subtract another positive integer (Ex: 3) continually until 0 or a negative value is reached, and then continually add the second integer until the first integer is again reached. For coding simplicity, output a space after every integer, including the last. Do not end output with a newline. Ex. If the input is: 12 3 the output is: 12 9 6 3 0 3 6 9 12arrow_forwardDesign a function that accepts an integer argument and returns the sum of all the integers from 1up to the number passed as an argument. For example, if 50 is passed as an argument, thefunction will return the sum of 1, 2, 3, 4, . . . 50. Use recursion to calculate the sum.arrow_forward
- Read Chapter 12 Recursive Lines Write a recursive function that accepts an integer argument, n. The function should display n lines of asterisks on the screen, with the first line showing 1 asterisk, the second line showing 2 asterisks, up to the middle line which shows n asterisks. You will then continue to print less stars until your last line of one asterisk. With an input of 3 your output should look like below. You will need to wind the stack to print up to your largest line. You will print the last set of lines as you unwind the stack or as you come out of your recursion. * ** *** ** *arrow_forwardProblem: Recursive Power Method Design a python 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 the exponent is a nonnegative integer. Write the main() function to input the required parameters as shown in thesample input/output. Sample Output:Average number of words per line: 26.0Enter a number: 2Enter a positive whole number between 1 and 100: 102.0 raised to the power of 10 is 1,024.00arrow_forwardC programming Language Recursion Question 1: Write c program to print the sum of the array elements using recursive function. You should have the main function + function to find the summation. Question 2: Write recursive function that returns the value of the following recursive definition: f(x) = 0 if x<= 0 f(x-1 )+ 2 otherwise You should have the main function + the recursive function.arrow_forward
