Write the definition of a function named printpoweroftwostars that receives a non-negative integer n and prints a line consisting of "2 to the n" asterisks. so, if the function received 4 it would print 2 to the 4 asterisks, that is, 16 asterisks: **************** and if it received 0 it would print 2 to the 0 (i.e. 1) asterisks: * the function must not use a loop of any kind (for, while, do-while) to accomplish its job

To accomplish this without using a loop,
we can use math on a string.

Example:
print("apple" * 8)

Output:
appleappleappleappleappleappleappleapple

In this example,
the multiplication by 8 actually creates 8 copies of the string.

So that's the type of logic we want to apply to our problem.

def powersOfTwo(number):
if number >= 0:
return print("*" * 2**number)
else:
return

Hmm I can't make indentations in this box,
so it's doesn't format correctly.
Hopefully you get the idea though.

We're taking the string containing an asterisk and copying it 2^(number) times.

Beyond that you will need to call the function below.
Test it with some different values.

powersOfTwo(4) should print 2^4 asterisks: ****************
