Question

E.g., given an array-backed list lst containing the elements [0, 1, 2, 3, 4, ..., 98, 99], the following code:

  for x in lst.poly_iter(2, 3, 4):
      print(x)

will produce the output:

  4
  9
  18
  31
  48
  69
  94

Programming rules:

• You must adhere to the same rules when using the built-in Python list as you did in the ArrayList lab.
• You may not use any other data structures (this includes the built-in Python list).

class ArrayList:
def __init__(self):
self.data = []
  
def poly_iter(self, a, b, c):
# YOUR CODE HERE

Answer 1

class ArrayList:

    #constructor

    def __init__(self):

        self.data = []

    #Creating List

    def poly_iter(self, a, b, c):

        lst = []

        for i in range(0, 100):

            lst.append(i)

            

        res = 0

        i = 0

        

        while True:

            res = (a*i*i)+(b*i)+c

            if res < lst[-1]:

                self.data.append(res)

            else:

                break

            i += 1

            

        return iter(self.data)

lst = ArrayList()

for x in lst.poly_iter(2, 3, 4):

    print(x)
