I need help answering this python question about recursion. Thanks!

Write code to complete print_factorial()'s recursive case. Sample output if user_val is 5: 51=5 * 4 * 3 * 2 * 1 = 120 1 def print_factorial(fact_counter, fact.value): 2 output_string = '' 3 4if fact_counter ==0: U Base case: 0! = 1 5 output.string += *1' 6 elif fact_counter =1: U Base case: print 1 and result 7 output.string += str(fact_counter) + * = * + str(fact_value) 8 else: # Recursive case 9 output.string += str(fact_counter) + ' * ' 10 next_counter = fact_counter - 1 11 next_value = next_counter * fact.value 12 output.string += "'Your solution goes here"' 13 14 return output_string 15 16 user_val = 5 17 printC'ftd! = ' % user.val, end="") 18 printCprint_factorial(user_val, user.val))
