Evaluate the postfix expression 6,5,2,3, +, 8, *, +, 3, +, * using stack.

How does the stack perform when left alone?

The operation of a stack removes and stores the top element of the stack.

suf: C nn.instru @ 2 S if the stack contains (from top) "5", "4", "3", "2", "1" and element = "new", the stack will contain "5", "4", "3", "new", "new" after interchange (). if the stack contains (from top) "5" and element "new", the stack will contain "new", "new" after interchange(). 30% Write public instanc method for MyStáck, called interchange (T element) to replac the bottom *two* items in the stack with element. wer than two items on the stack, upon return the stack should contain exactly two items that are element. Examples: F2 # ۲ 3 ۳ WE E ص X Assume class MyStack implements the following StackGen interface. For this question, make no assumptions about the implementation of MyStack except that the follo wing interface methods are implemented and work as documented. public interface StackGen { void push(T 0); // conventional stack behavior T pop(); // conventional stack behavior T top(); // returns, but does not remove, top element in stack boolean isEmpty(); // returns true…
