Chapter 18, Problem 8PC
Program Plan Intro
Stack Copy Operations
Program Plan:
- Declare the main function.
- Prompt the user to enter a postfix expression.
- Convert an input stream into a string stream.
- Evaluate the postfix expression by calling the postfixExpr function and print the result.
- Skip whitespace in an input stream while evaluating a postfix expression.
- Declare a Function postfixExpr that evaluates the postfix expression by considering if the next token in the input stream is an integer, read the integer and push it onto the stack using the push() operation of the stack .
- However, if the input stream is an operator, pop the last two values from the stack using the pop operation and apply the operator, and push the result onto the stack and the lone value is the result and look for next iteration.

Stack:
Stacks are a type of container with LIFO (Last In First Out) type of working, where a new element is added at one end and (top) an element is removed from that end only. Your Stack should not be of the fixed sized. It should be able to grow itself. So using the class made in task 1, make a class named as Stack, having following additional functionalities:
bool empty() : Returns whether the Stack is empty or not. Time Complexity should be: O(1)
bool full() : Returns whether the Stack is full or not. Time Complexity should be: O(1)int size() : Returns the current size of the Stack. Time Complexity should be: O(1)Type top () : Returns the last element of the Stack. Time Complexity should be: O(1)
void push(Type) : Adds the element of type Type at the top of the stack. Time Complexity should be: O(1)
Type pop() : Deletes the top most element of the stack and returns it. Time Complexity should be: O(1)
Write non-parameterized constructor for the above class.

C#
Reverse the stack - This procedure will reverse the order of items in the stack. This one may NOT break the rules of the stack. HINTS: Make use of more stacks. Arrays passed as parameters are NOT copies. Remember, this is a procedure, not a function.
This would occur in the NumberStack class, not the main class. These are the provided variables:
private int [] stack;private int size;
Create a method that will reverse the stack when put into the main class.
1. Stack Implementation
Write a method called insert for the class Stack. The method shall be
implemented using an array-based structure. You can assume that String[]
stack is defined in the class, which is responsible to store the elements and
responsible to enforce the order of first-in last-out, a.k.a., FIFO. Additionally, you
can assume there is a pointer called top, that indicates the position of the top of
the stack, pointing to the next available position to insert.
The method shall:
• take a String s as a parameter, and shall add it at the top of the stack.
shall return true if the element s was added successfully at the top of the
stack, false otherwise.
.
. The method must check boundaries of capacity and limitation of the Stack. In
case the method is invoked to insert an element of the top of the stack that
exceeds its current capacity, the method shall handle the situation properly.
Do not provide the entire Stack implementation, only the code solution of the
method.

As a singly linked list's node references both its predecessor and its successor, it is easily possible to traverse such a list in both directions. According to the terminology introduced in class, the head reference variable in a singly linked list object references the list's first node. According to the terminology introduced in class, in a doubly linked list, each node references both the head and tail node. In a double-ended singly linked list, the tail reference variable provides access to the entire list. In a circular linked list, the last node references the first node.arrow_forward
