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 list
IN PYTHON Linked Lists Consider the implementation of the Linked list class, implement the following functions as part of the class: index(item) returns the position of item in the list. It needs the item and returns the index. Assume the item is in the list.   pop() removes and returns the last item in the list. It needs nothing and returns an item. Assume the list has at least one item.   pop_pos(pos) removes and returns the item at position pos. It needs the position and returns the item. Assume the item is in the list.   a function that counts the number of times an item occurs in the linked list a function that would delete the replicate items in the linked list (i.e. leave one occurrence only of each item in the linked list) Your main function should do the following: Generate 15 random integer numbers in the range from 1 to 5. Insert each number (Item in a node) in the appropriate position in a linked list, so you will have a sorted linked list in ascending order. Display the…
Answer the following in your own words: 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 ended linked list). They said this significantly improved the performance for all functions (push, pop, search, and update). Are they correct? Why or why not? Another friend implemented a queue as a linked list with only a head pointer (no tail node). She said this made performance of all functions (insert, remove, search, and update) categorically equal to a queue as a linked list with a head and a tail node. Is she correct? Why or why not?

Use Java : Delete N Nodes After M Nodes of a Linked List You are given the head of a linked list and two integers m and n.Traverse the linked list and remove some nodes in the following way:- Start with the head as the current node.- Keep the first m nodes starting with the current node.- Remove the next n nodes- Keep repeating steps 2 and 3 until you reach the end of the list.Return the head of the modified list after removing the mentioned nodes
Create a collection. Along with GETMAX, MAXSTACK offers the ADT commands PUSH, POP, and EMPTYSTACK and performs similar operations to a standard linked stack. The GETMAX function keeps track of the largest stack member. Can the collection be constructed using GETMAX, which only requires O(1) time complexity? don't copy old bartleby answer it's wrong
Question : Write a program to remove duplicates from a doubly linked list. e.g (1,2,3,4,5,2) (you will remove the 2nd duplicate) and then swap two data items in a doubly linked list. swap address of node 2 with node 4.
1-Write a C program to show operations on a singly linked where each node consists of integers. (a) Insert (At beginning, At end) (b) Delet (At beginning, At end) (c) Search (d)reverse (e) Print middle element 2 Write a C program using dynamic variable & pointers to construct a singly linked list consisting of the following information in each node. Student id (integer), student name (character string) & semester (integer). 3 Write a C program using dynamic variables & pointers to construct an ordered (ascending) singly linked list based on the rank of the student, where each node consists of the following information student id( integer) student name(character), rank(integer).
In 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.
Suppose a node of a linked list is defined as follows in your program: typedef struct{ char data; struct Node* link; } Node; Write the definitions of two functions (i) Node* pop(Node* top) – which removes the top element of the stack, and (ii) bool compare(Node* topA, Node* topB) - which returns true if the both stacks have identical data. The function returns false if the data in both stacks are not identical. In the function definitions, top, topA, and topB point the top elements of corresponding stacks. You must use the following function definitions in your answer. The peek function has already been defined. You need to write the definition of pop and compare functions. You are not allowed to modify the parameters and/or return types of the functions. Node* pop(Node* top){ //write the function definition } char peek(Node* top){ return top->data; } bool compare(Node* topA, Node* topB){ //write the function definition } Write the time complexity in Big-O notation…
Consider the implementation of the Ordered Linked list class, implement the following functions as part of the class definition: ▪ index(item) returns the position of item in the list.

Assume the list has at least one item.   ▪ pop_pos(pos) removes and returns the item at position pos. It needs the position and returns the item.
