- Your job is to implement a Stack using only a Queue(s). That is, you will be responsible for writing the push and pop methods for a Stack but your internal data representation must be a Queue: void push(Queue& queue, int element) int pop(Queue& queue)... QUESTION 1 A palindrome is a string that reads the same both forward and backward. For example, the string "madam" is a palindrome. Write a function, isPalindrome, check whether a string is a palindrome using stack and queue. No credit will be given if you are not using stack and queue. When compares each letter, you need to convert each letter to capital letter. Use toupper() Lo convert each letter to capital. Assume that the following object has created. queue q; stack s; Use the following function declaration. bool isPalindrome (string s) For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

- 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.Select true or false for the statements below. Explain your answers if you like to receive partial credit 4) Given a stack implemented as a standard linked list (only a head pointer) with O(1)push and O(1) pop, and the following functions are performed in sequence:Push(“Charmander”), Push(“Squirtle”), Push(“Bulbasaur”), Pop(), Push(“Larvitar”),Push(“Eevee”), Pop(), Pop()Which of the following is true after all the functions are executed?a. Charmander and Squirtle will be the only elements left on the stackb. The head node will be pointing to Charmanderc. If you Push(“Pikachu”), it will be the last node of the linked listC++ The task is to undo the order of the elements of the Linked List using an auxiliary Stack. Develop a backtracking program which apply stack concept. Use linked list to store the node. p/s: this is undo and not reverse For the questions prepare: Program description - describe in detail about the scenario solve by your program. Coding Complete sample out with appropriate label and explanation.
- 1. Assume you have a queue with operations: enqueue(), dequeue(), isEmpty(). How would you use the queue methods to simulate a stack, in particular, push() and pop() ? Hint: use two queues, one of which is the main one and one is temporary.Develop an application in java language that stores characters A, B and C in a queue array and then displays both the size and the first-in element of the stack. The application should then remove the first element of the queue and then display both the size and the first-in element of the queue again. Appropriate queue methods should be used to add, delete and display characters.Consider the following code segment , The variable q is an object of type Queue, the variable s is an object of type Stack. peek method looks at the first element in the queue without removing it. the remove method removes the first element from the queue. add method adds an element to the and of the queue or add an element to the top of the stack. pop method removes an element from the top of the stack What would be the content of the variable q (8 numbers) after we complete the second while loop in the code for (int i = 30; i <= 40; i ++) { if(i % 3 == 0) q.add(i); } while (!q.isEmpty()) { s.add(q.peek()); s.add(q.peek()); q.remove(); } while (!s.isEmpty()) { q.add(s.pop()); }
- Queues and stacks can be implemented by using linked list structure. To implement "pop" and "push" methods of stack, ... and .. methods of linked list can be used, respectively. To implement "enqueue" and "dequeue" methods of queue, .. and. methods of linked list can be used, respectively. Fill in the blank with correct answers. O pop_front - push_back - pop_back - push_back O pop_back - push_front - pop_front - push_front pop_back - push_back - pop_front - push_back O push_back - pop_back - push_back - pop_frontThe following function is supposed to print the last Kelements of a linked list in reverse order using stack. The function code is incomplete. You are expected to fill in (1), (2), and (3) with a single line of code for each. 1- void function(Node* head, int k) { Node *cur = head; if (cur 2 3 NULL) 4 return; 5 6 Stack st; 7 8 - while (cur != NULL) { 9 //fill in here (1) 10 //fill in here (2) 11 } 12 13 int counter 0; %3D 14 while (counter < k) { cout <« st.top() < //fill in here (3) counter++; } 15 - 16 17 18 19 20 } Your answerIn C++, Write a program using linked list (not STL List) and mimic the stack push and pop operations in list's insert and delete functions. If you don't know about stack, stack follows Last In First Out (LIFO) pattern. Any item inserted in the stack first can be removed at last. Your linked list's insert and delete functions should insert the nodes in the linked list in such a way that the last inserted item could be removed first and first element could be removed last. For insertion, a node must be inserted from back end (not at head or middle) You can use the following structure for the node or any other of your choice. struct Node { int data; Node * next; }; Note: Write constructors (if applicable), use menu to offer choice to the user such as insert, delete, display , size and exit.
