TRUE or FALSE? Answer the following question and state the reason why:
- cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list.
- In a Dynamic Stack, the pointer top stays at the head after a push operation.
- During a Pop operation in Static Stack, the elements are being moved one step up.
- In a dynamic implementation of stack, the pointer top has an initial value of null.
Step by step
Solved in 3 steps
- TRUE or FALSE? Answer the following question and state the reason why: A circular linked list has 2 node pointers. cout<<list.back()<<endl; = The back member function returns a reference to the last element in the list. In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null.TRUE or FALSE? Please answer the following question and state the reason why: Thank you! In a Dynamic Stack, the pointer top stays at the head after a push operation. During a Pop operation in Static Stack, the elements are being moved one step up. In a dynamic implementation of stack, the pointer top has an initial value of null. STL empty function will yield a value of true if the stack has elements.Please be thorough with explanation (a) Consider implementing a stack as a class that relies on a singly linked list, maintaining pointers to both the start and end of the singly linked list in the main object. You consider two possibilities. The first is to push (insert) to the beginning and pop (remove) from the beginning of the linked list. The second is to push to the end and pop from the end of the linked list. Is one of these possibilities better than the other? Briefly explain your answer.
- Modify the C++ class for the abstract stack type shown belowto use a linked list representation and test it with the same code thatappears in this chapter. #include <iostream.h>class Stack {private: //** These members are visible only to other//** members and friends (see Section 11.6.4)int *stackPtr;int maxLen;int topSub;public: //** These members are visible to clientsStack() { //** A constructorstackPtr = new int [100];maxLen = 99;topSub = -1;}~Stack() {delete [] stackPtr;}; //** A destructorvoid push(int number) {if (topSub == maxLen)cerr << "Error in push--stack is full\n";else stackPtr[++topSub] = number;}void pop() {if (empty())cerr << "Error in pop--stack is empty\n";else topSub--;}int top() {if (empty())cerr << "Error in top--stack is empty\n";elsereturn (stackPtr[topSub]);}int empty() {return (topSub == -1);} }5) Run a generic data structure that is a deque that supports insertions and deletions at both ends but, depending on the user's selection, works as a stack or a queue.3.Write a generic class called GenericStack<T> that represents a stack structure. A stack structure follow the strategy last-in-first-out, which means that the last element added to the stack, is the first to be taken out. The GenericStack class has the following attributes and methods: --An attribute ArrayList<T> elements which represents the elements of the stack.(All of you refer collection framework for ArrayList. or you can use an array to hold the elements of Stack.)[Refer the following links to have intro on ArrayList: https://www.w3schools.com/java/java_arraylist.asp, https://www.geeksforgeeks.org/arraylist-in-java/] --A constructor that creates the ArrayList or an Array --A method push(T e) which adds the element to the ArrayList<T> or array. --A method pop() which removes the last element of the ArrayList<T> (last element added), if the list is not already empty and returns it. --A method print() which prints the elements of the stack starting from the…
- Short answer: Answer the following in your own words: 1) Your friend says they implemented a stack as a linked list with reference pointers to both a head and the tail node (i.e. they implemented a stack as a double endedlinked list). They said this significantly improved the performance for all functions (push, pop, search, and update). Are they correct? Why or why not?Write a generic class called GenericStack<T> that represents a stack structure.

- Refer to the code fragment below and convert the following Queue structure into a Stack structure. You should create a reference called S1 for the stack structure. Code: Queue Q1 = new LinkedList (); Q1.add(“Sandra”); Q1.add (15); Q1.add (200); Q1.add (‘# ‘); Q1. remove (); System.out.println(Q1); System.out.println(Q1.peek()); Q1.add(“Mary”); System.out.println(Q1);Answer it fast and correct. Don't stuck. i ll rate Fill in the underlines below to complete a function template, reverseStack, that takes as a parameter a stack object and uses a queue object to reverse the elements of the stack. C++ code Answer: template <class Type> void reverseStack(stackType<Type> &s) { linkedQueueType<Type> q; Type elem; while (_________________) // The stack is not empty. { // Copy the top element of the stack into the queue //and remove it from the stack. elem = _________________; _________________; _________________; } while (_________________) // The queue is not empty. { // Copy the front element of the queue into the stack //and remove it from the queue. elem = _________________; _________________; _________________; } }S and Q are integer stacks and priority queues, respectively. C mod 3 is the priority of an element C joining the priority queue Q. In other words, the elements' priority numbers are either 0 or 1 or 2. What is the output of the following code if A, B, and C are integer variables? However, the queue procedures have been modified to work on a priority queue. 1.A = 102.B = 113.C = A+B4.while (C < 110) do5. if (C mod 3) = 0 then PUSH (S,C)6. else ENQUEUE (Q,C)7. A = B8. B = C9. C = A + B10.end11.while not EMPTY_STACK (S) do12. POP (S,C)13. PRINT (C)14.end15.while not EMPTY_QUEUE (Q) do16. DEQUEUE (Q, C)17. PRINT (C)18.end
