Question

3.5.1: Recursive function: Writing the base case.

Add an if branch to complete double_pennies()'s base case.

Sample output with inputs: 1 10

Number of pennies after 10 days: 1024

# Returns number of pennies if pennies are doubled num_days times
def double_pennies(num_pennies, num_days):
total_pennies = 0

if "solution goes here"

else:
total_pennies = double_pennies((num_pennies * 2), (num_days - 1))

return total_pennies

# Program computes pennies if you have 1 penny today,
# 2 pennies after one day, 4 after two days, and so on
starting_pennies = int(input())
user_days = int(input())

print('Number of pennies after', user_days, 'days: ', end="")
print(double_pennies(starting_pennies, user_days))
