2. Extended programming exercise on stack: a) Two stacks of the same type are the same if they have the same size and their elements at the corresponding positions are the same. Write a function that will return true if two stacks of the same type are the same and false otherwise. b) Add the following operation to the stack class in order to copy the elements of a stack in reverse order to another stack. void reversestack (....) ; c) Write the implementation of the function and test the function. d) Repeat the programming exercise for linked-list implementation
