Using Java, write a MyStack class that implements the StackInterface using a linked list. Your MyStack class is required to use a private inner class implementation for the node of the linked list called Node. In addition to implementing the methods defined in StackInterface, your MyStack class must override the toString method defined in the Object class. toString should return the String representation of the current state of MyStack. For example, if we created a new MyStack object and pushed 256, 1, 9, 20, and 2018 onto the stack, the toString method should return: TOP: 2018 | 20 | 9 | 1 | 256 |
