100p, use the previously created push(functio... Since you need to reverse the whole string, and strings can have different lengths, the optimal way to solve this is with the while - loop and the is_empty() function. You can get the length of a string with the len() function. Use the is_empty() function on the stack to check if the stack is empty or not. Did you use the is_empty() function? 1 #All function that you have implemented in the previous steps 2 def push(stack, new_item): 3 stack.append(new_item) 4 5 def is_empty(stack): 6 return stack == [] 7 8 def size( stack): 9 return len(stack) 10 11 #Do not change any code above this line. 12 13 I 14 def reverse_string(string): 15 #We have defined the stack for you 16 stack = [] 17 18 for char in string: 19 def push(stack, char): 20 stack.append(chex) #push to stack 31 x + main.py X starter_code.py He have us CU TIC LAN TOL you stack = [] 16 17 18 19 for char in string: def push(stack, char): stack.append(char) #push to stack 20 21 22 23 new_string=" 24 25 26 while not --- #Check if the stack is empty new_string += " + #pop the last element 27 return new_string 28 29 30 #Tests 31 #Do not change code below this line 32 assert reverse_string("programming") == "gnimmargorp" 33 print("Awesome job!") 34 print(reverse_string("programming")) 35
