Question

def removeMultiples(x, arr) - directly remove the multiples of prime numbers (instead of just marking them) by creating a helper function. This recursive function takes in a number, n, and a list and returns a list that doesn’t contain the multiples of n.

def createList(n) - a recursive function, createList(), that takes in the user input n and returns an array of integers from 2 through n (i.e. [2, 3, 4, …, n]). 

def Sieve_of_Eratosthenes(list) -  a recursive function that takes in a list and returns a list of prime numbers from the input list.

Template below:

def createList(n):
    #Base Case/s
    #ToDo: Add conditions here for base case/s
    #if <condition> :
        #return <value>
  
    #Recursive Case/s
    #ToDo: Add conditions here for your recursive case/s
    #else:
        #return <operation and recursive call>

    #remove the line after this once all ToDo is completed
    return []

def removeMultiples(x, arr):
      #Base Case/s
    #TODO: Add conditions here for your base case/s
    #if <condition> :
        #return <value>
  
    #Recursive Case/s
    #TODO: Add conditions here for your recursive case/s
    #else:
        #return <operation and recursive call>

    #remove the line after this once you've completed all ToDo
    return []
   
def Sieve_of_Eratosthenes(list):
  #Base Case/s
  if len(list) < 1 :
    return list
  #Recursive Case/s
  else:
    return  [list[0]] + Sieve_of_Eratosthenes(removeMultiples(list[0], list[1:]))

if __name__ == "__main__":
  n = int(input("Enter n: "))
  print(n)
  list = createList(n)
  #Solution 1
  primes = Sieve_of_Eratosthenes(list)
  print(primes)

The code is already given above.
Problem: Using PYTHON, create and implement a recursive function that will do the following:
Input #1
Output #1
10
Enter n: 10
[2, 3, 5, 7]
Input #2
Output #2
Enter n: 50
50
[2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47]
V The input is a single integer value. This value will be the upper bound of the list of values that will be created using
the createList() function.
V The input is an integer from the range [2,200] (inclusive). Assume that the input is always valid.
Output:
V The output will be a list containing primes within the range of 2 to n (inclusive), where n is the value of the user's input.
