PP 12.4 The array implementation in this chapter keeps the top variable pointing to the next array position above the actual top of the stack. Rewrite the array implementation such that stack[top] is the actual top of the stack. PP 12.5 There is a data structure called a drop-out stack that behaves like a stack in every respect except that if the stack size is n, when the n + 1 element is pushed, the first element is lost. Implement a drop-out stack using an array. (Hint: A circular array implementation would make sense.)

PP 12.4 The array implementation in this chapter keeps the top variable
pointing to the next array position above the actual top of the
stack. Rewrite the array implementation such that stack[top] is
the actual top of the stack.
PP 12.5 There is a data structure called a drop-out stack that behaves like
a stack in every respect except that if the stack size is n, when
the n + 1 element is pushed, the first element is lost. Implement a
