- detemine if the follow statement are true or False and why? screenshots show the ArrayBoundedStack class and StackUnderflowException code If N represents the number of elements on the stack, then the push method of the ArrayBoundedStack class is O(N). While processing this expression ( } ( ) ( ) { { { } [ ] } } ) the highest number of elements on our stack at any one time is 1. If N represents the maximum possible number of elements on the stack, then the ArrayBasedStack constructor is O(N). The following expression is balanced: ( ( ( [ ) ] ) ) Our StackUnderflowException code essentially consists of two simple constructors and "packages" and "extends" statements and nothing else.Stacks can be used to evaluate a post-fix expressions. What is the result if the following postfix expression is evaluated? ´ 7 7 2 3 + 8 * + 3 + *Create your own called class called Stack Your class should store items transparently. You should add items using a Push method and remove them through the Pop method. Add an IsEmpty method should return whether there are any items in the stack or not. A CountItems method should tell you the current number of items in the stack Write some code to test your Stack class using the shapes in part 1.
- In the following code, assume myStack is a stack that holds integers. What would be the contents of the stack after the following operations, indicating what element is currently at the top and the bottom of the stack. myStack.push(1);myStack.push(2);myStack.push(3);myStack.pop();myStack.push(4);myStack.push(5);myStack.pop(); Group of answer choices 4 <- Top21 <- Bottom 5 <- Top31 <- Bottom 4 <- Top32 <- Bottom 5 <- Top21 <- BottomWhich of the following is NOT an operation supported by a stack interface? Push Clear Insert PeekC# 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. public void ReverseStack(){ }

Using the provided 3 char airport codes, create a 6 character string that is the origin & destination city pair. Create all the possible…1. Use a below-given starter code. Use StackInterface.(h), and ArrayStack.(h,cpp). You will write your own StackDriver.cpp application file. IT'S IN C++Also...If the class that you create is Star, remember that you will declare your stack as follows:ArrayStack<Star> myStarStack;and you will push, pop, and peek Star objects.2. Create your own class definition. I should have at least one attribute, a constructor, and set and get methods for each attribute in your class.NOTE: If your class is offensive your lab will be rejected and you will receive a score of zero. I'm sorry I have to say this but there is a history of this happening and it is not appropriate.3. Write a driver program that exercises the Stack class from the downloaded starter code. Create multiple instances of your own class and demonstrate the stack operations: push, pop, and peek. ( you write your own class that you will put on the stack and you will write a driver that pushes, peeks, and pops your class items…Create a menu driven application that will implement a stack and the user will be asked about the size of an array they wanted.
- C# Assume you have a LinkedList of Node objects. Both classes have all the normal operations shown below. Your job is to program the DeleteTail method of the LinkedList class. This method locates and deletes the last element of the linked list. You may not change its signature line. Keep your code clean, but no documentation is necessary. A good solution will be between 5 and 10 lines of code, not counting whitespace.Question 1 (20 marks)Refer to the operations below:Add (10 + 5)Add (4+8)Add (7*2)Add (90 – 3)Print listPrint peekRemove an item from the listPrint list1.1 Implement the operations above into a Queue structure called q1. (10)1.2 Implement the operations above into a Stack structure called s1. (10)Question 2 (20 marks)Create a complete java program called Week_Report. The program must include two array structures, astring array called DaysOfWeek and a double array called Temp_Values. Store in the DaysOfWeek arraythe following values (Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday). Store in theTemp_Values array the following (23.5, 34.0, 20.9, 45.7, 29.3, 34.5, 32.5). Using a for loop structure outputthe values for the two arrays.Day of the Week Temperature ValuesMonday 23.5Tuesday 34.0Wednesday 20.9Thursday 45.7Friday 29.3Saturday 34.5Sunday 32.5C# 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.
