Please do the following in sequence

1. Implement stack using user defined functions as demonstrated in the class(you may use the online book)

2. Add the following functions in your Stack class and implement

• void printStack(Stack s)prints the elements in stack s from top to bottom. When printStack returns, s should be unchanged.

• Stack reverseStack(Stack s)returns a new stack whose elements are backwards from those in s. Again, s is unchanged.

Please code in python 3
