A palindrome is a string that reads the same front to back as it does back to front, such as "racecar". Solve the palindrome question using a Stack class, implemented as a linked list, (not an array) (you must code it - do not use the library Stack class), and a Queue class implemented as a linked list, (not an array) The Stack class should have a constructor, pop, push, and isEmpty methods. The Queue class should have a constructor, enqueue, dequeue, and isEmpty methods. Each class will have a private embedded Node class.
