Question

write a program to implement reversal of a string using stack data structure in list of numbers

Answer 1

class Stack:
    def __init__(self):
        self.list = []

    def add(self, value):
        self.list.append(value)

    def pop(self):
        if self.list:
            return self.list.pop()

string = input()
stack1 = Stack()
for ch in string:
    stack1.add(ch)
reversed_string = ''
ch = stack1.pop()
while ch:
    reversed_string += ch
    ch = stack1.pop()
print(reversed_string)
