Question

Write python code to complete factorial_str()'s recursive case.

Sample output with input: 55! = 5 * 4 * 3 * 2 * 1 = 120

def factorial_str(fact_counter, fact_value):
output_string = ''

if fact_counter == 0: # Base case: 0! = 1
output_string += '1'
elif fact_counter == 1: # Base case: print 1 and result
output_string += str(fact_counter) + ' = ' + str(fact_value)
else: # Recursive case
output_string += str(fact_counter) + ' * '
next_counter = fact_counter - 1
next_value = next_counter * fact_value
output_string += '''Need help here to get the proper output'''

return output_string

user_val = int(input())
print('{}! = '.format(user_val), end="")
print(factorial_str(user_val, user_val))
