### Linked List Removal FunctionA student implementing a linked list wrote this method:```cppbool LinkedList::Remove(int e) { for (Node *ptr = _head; ptr != nullptr; ptr = ptr->next) { if (e == ptr->element) { Node *deleteMe; deleteMe = ptr->next; ptr->element = ptr->next->element; ptr->next = ptr->next->next; delete deleteMe; return true; } } return false;}```### Linked List Test CaseThe student tested it with this linked list:- **Linked List Diagram**: - _head -> 1 -> 2 -> 3 -> nullptr### Issue DiscoveredStrangely, the student found that it worked perfectly except it crashed with a segmentation fault for only one value.- **Question 1**: What was the value of `e` that made it crash? - **Question 2**: What was the number of the line where it crashed? ### Analysis of the CrashThe issue likely occurs when trying to access or delete a node reference that doesn't exist, particularly when `ptr->next` or `ptr->next->next` is null, leading to undefined behavior or a segmentation fault.

What was the value of e that made it crash? 3 What was the number of the line where it crashed? 7

Assume the following method is within the SingleLinkedList class. What does it do? public void unknownMethod () { Node pt head; E temp; while (pt != null && pt.next != null) { temp pt.data; = pt.data pt.next.data; pt.next.data= temp; pt pt.next; } }
JAVA please Given main() in the ShoppingList class, define an insertAtEnd() method in the ItemNode class that adds an element to the end of a linked list. DO NOT print the dummy head node. Ex. if the input is: 4 Kale Lettuce Carrots Peanuts where 4 is the number of items to be inserted; Kale, Lettuce, Carrots, Peanuts are the names of the items to be added at the end of the list. The output is: Kale Lettuce Carrots Peanuts Code provided in the assignment ItemNode.java:
lst1= [4,3,2,6,2] and lst2=[1,2,4] then the new_list is [2,2,4]. Assign the new-list to variable new_list and sort. Code: What is wrong with this code? lst1= [4,3,2,6,2] lst2=[1,2,4] new_list=[] for elements1 in lst1: for elements2 in lst2: elements1==elements2: new_list.append(elements1) new_list.sort()

Make a doubly linked list and apply all the insertion, deletion and search cases. The node willhave an int variable in the data part. Your LinkedList will have a head and a tail pointer.Your LinkedList class must have the following functions: 1) insert a node1. void insertNodeAtBeginning(int data);2. void insertNodeInMiddle(int key, int data); //will search for keyand insert node after the node where a node’s data==key3. void insertNodeAtEnd(int data);2) delete a node1. bool deleteFirstNode(); //will delete the first node of the LL2. bool deleteNode(int key); //search for the node where its data==keyand delete that particular node3. bool deleteLastNode(); //will delete the last node of the LL3) Search a node1. Node* searchNodeRef(int key); //will search for the key in the datapart of the node2. bool searchNode(int key); The program must be completely generic, especially for deleting/inserting the middle nodes. Implement all the functions from the ABOVE STATEMENTS and make a login and…

When removing curNode from a doubly-linked list with at least 2 elements, the list's tail may be assigned with Group of answer choices curNode curNode's predecessor curNode's successor null
java program : Given the following method to be considered within the SingleLinkedList class, what does this method do? public void Undefined() { Node<E> ptr = head; if (ptr == null || ptr.next == null) return false; E item1 = ptr.data; while (ptr.next != null) ptr = ptr.next; E item2 = ptr.data; if (item1.equals(item2)) { head = head.next; size--; } } If the first element of the list is equal to the second element of the list, then the method deletes the second node. If the first element of the list is equal to the last element of the list, then the method deletes the first node. If the first element of the list is equal to the second element of the list, then the method deletes the first node. If the first element of the list is equal to the last element of the list, then the method deletes the last node.
An approach to remove nodes from a linked list that have the same key is provided.
Given the doubly linked list: head tail 10 20 30 60 40 50 assuming that the Node class has three fields: prev, info, and link, what will be the list after performing the following operations?
