# recursive function

### Resolved Question:

(q1) Write a recursive function called power_of_2 that takes as parameter a number N and returns 2N. Use the fact that 2N is 2 multiplied by itself N times. DO NOT USE THE ** operator!

(q2) Write a recursive function called square_sum that takes a parameter a number N and returns the sum 12 + 22 + 32 + ... + N2.

(q3) Write a recursive function called listProd for the following problem: You are given as inputs: a list L of numbers, and a number N (which is the length of the list); need to compute and return the product of all the numbers in the list (that is L[0] * L[1] * L[2] * ... * L[N-1]).

Were you able to retrieve it? You can open it in any text editor to view the code, or open in Python GUI and run the program.
