Problem:Given two linked lists sorted in increasing order. Merge them both in such a way that the result list is in decreasing order. Both the Linked list can be of different sizes. /* The structure of linked list is the following struct Node { int data; Node* next; }; */ struct Node * mergeResult(Node *node1,Node

Problem Description: Given a singly linked list: A0→A1→→An-1→An,reorder it to: A0→An→A1→An-1→A2→An-2→ Given 1->2->3->4->5 its reorder is 1->5->2->4->3. It is recommended do this in-place without altering the nodes’ values. Input: In this problem, methodtakes one argument: Address of the head of the linked list. The function should not read any input from stdin/console. The node structure
Problem Description: Sort the given doubly linked list using quicksort. Just complete the partition function using quicksort techniquetry to solve it in O(1) space . Input: In this problem, method takes two argument: the node1 and node2. The function should not read any input from stdin/console. The struct Node has a data part which stores
Description: Given a linked list,performs the following task Remove alternative nodes from second node Reverse the removed list. Append the removed list at the end. Input : You have to complete the method which takes oneargument: the head ofthe linked list. You should not read any input fromstdin/console. The struct Node has a data part

Problem Description: Given a linked list, write a function to reverse every k nodes (where k is an input to the function).Ifalinked list is givenas1->2->3->4->5->6->7->8->NULL and k = 3 then output will be3->2->1->6->5->4->8->7->NULL. Input: In this problem,method takes two argument: the head of the linked list and int k. You should not read any input

Problem description: Given a singly linked list, remove all the nodes which have a greater value on right side. Input: You have to complete the method which takes 1argument: the head of the linked list .You should not read any input from stdin/console.There are multiple test cases. For each test case, this method will be
