Implement an algorithm to delete a node in the middle (i.e., any node but the first and last node, not necessarily the exact middle) of a singly linked list, given only access to that node. EXAMPLE lnput:the node c from the linked list a->b->c->d->e->f Result: nothing is returned, but the new linked list looks like a ->b->d->e->f

8. Write down the insertBefore method which inserts a new element in the list before the node containing the given element. The method takes as parameters a dummy headed doubly linked circular list, the element existing in the list and new element to be added. public void insertBefore (Node head, Object elem, Object newElement) { //to do OR def insertBefore (head, elem, newElement): pass insertBefore (head, 3, 50) Sample Input Sample Output Ox21 2 223 240 O x21 2 22 50 ² 3 2 4 0

You have two numbers represented by a linked list, where each node contains a singledigit. The digits are stored in reverse order, such that the 1 's digit is at the head of the list. Write afunction that adds the two numbers and returns the sum as a linked list.EXAMPLEInput: (7-> 1 -> 6) + (5 -> 9 -> 2).That is,617 + 295.Output: 2 -> 1 -> 9. That is, 912.FOLLOW UPSuppose the digits are stored in forward order. Repeat the above problem.Input: (6 -> 1 -> 7) + (2 -> 9 -> 5).That is,617 + 295.Output: 9 -> 1 -> 2. That is, 912.

Given a singly linked list of integers, reverse the nodes of the linked list 'k' at a time and return its modified list. 'k' is a positive integer and is less than or equal to the length of the linked list. If the number of nodes is not a multiple of 'k,' then left-out nodes, in the end, should be reversed as well.Example :Given this linked list: 1 -> 2 -> 3 -> 4 -> 5 For k = 2, you should return: 2 -> 1 -> 4 -> 3 -> 5 For k = 3, you should return: 3 -> 2 -> 1 -> 5 -> 4 Note :No need to print the list, it has already been taken care. Only return the new head to the list. Input format :The first line contains an Integer 't' which denotes the number of test cases or queries to be run. Then the test cases follow. The first line of each test case or query contains the elements of the singly linked list separated by a single space. The second line of input contains a single integer depicting the value of 'k'. Remember/Consider :While specifying the list…

Implement a method to remove a node from the centre of a singly linked list—that is, any node other than the first and end nodes—with access to only that node.EXAMPLEThe node C from the linked list a->b->c->d->e->f should be entered.Nothing is returned as a result, although the new linked list has the shape of an a->b->d->e->f

Extend the LinkedList class adding a newmethod printMiddle that prints values of the middle node(s) of a linkedlist in one pass. Assume that we do not know the size of the linked listahead of time.Note that if the list has an odd number of nodes, there will be onlyone middle node; otherwise, there will be two middle nodes.E.g., applying printMiddle to the linked list [1 → 7 → 5 → 4 → 2],we get 5; applying it to [1 → 2 → 3 → 4 → 5 → 6], we get 3 and 4.Extra1. You may get 5 extra points for each of the problems 1.a,1.b, and 2 (15 points in total)2. To this end, you have to explain3 whichof the following classes of runtime complexities better characterizes yourmethod – O(log n), O(n), O(n2), or O(2n). Simply briefly write it in thecomments after the method declaration. For example, for the look-upfunction indexOf, your explanation might look like:public int indexOf(int element) {// O(n): Since we need to iterate over// the entire array to find the number.// This number may be at the end…
