Let x = (X,. X2X,) and y (y,Y2-Ym) to be two linked lists. Assume that in each list, the nodes are in non- decreasing order of their data field values. Write an algortihm to merge the two lists together to obtain a new linked list z in which the nodes are also in this order. Following the merge, x and y do not exist as individual lists. Each node initially in x or y is now in z. No additional nodes may be used. What is the time complexity of your algorithm?

Given two (singly) linked lists, determine if the two lists intersect. Return the intersecting node. Note that the intersection is defined based on reference, not value. That is, if the kthnode of the first linked list is the exact same node (by reference) as the jth node of the secondlinked list, then they are intersecting.
What is the difference between a single and doubly linked list? When might a singly-linked list be preferable than a doubly-linked list? When might a doubly-linked list be preferable than a singly-linked list? How many nodes will be visited during a search for a node that is in a linked list with N nodes? Describe the best- and worst-case scenarios for a search. Explain why a singly-linked list has the RemoveAfter() function while a doubly-linked list has the Remove() function. Is it possible to create a RemoveAfter() method for a doubly-linked list as well? Explain why you think that is or why you don't think that is. Is it possible to create a Remove() method for a singly-linked list as well? Explain why you think that is or why you don't think that is.
Suppose there are two singly linked lists both of which intersect at some point and become a single linked list. The head or start pointers of both the lists are known, but the intersecting node is unknown. Also, the number of nodes in each of the list before they intersect are unknown and both the list may have it different. List1 may have n nodes before it reaches intersection point and List2 might have m nodes before it reaches intersection point where m and n may be m = n, m > n or m < n. Give an algorithm for finding the merging point. Hints: A brute force approach would be to compare every pointer in one list with every pointer in another list. But in this case the complexity would be O(mn)
13) A linked list is given and the number of the nodes in this linked list is not known. You have to find the sum of the last "x" nodes of the linked list in a single traversal. Assume that size of the linked list is larger than "x". Explain your approach in brief. What is Big-O notation of this solution?

In what situation would you use a doubly-linked list over a singly-linked list? If a node is in a linked list with N nodes, how many nodes will be traversed during a search for the node? Explain the best- and worst-case search scenarios. Explain why a singly-linked list defines a RemoveAfter() function, while a doubly-linked list defines a Remove() function. Could a RemoveAfter() function also be defined for a doubly-linked list? Explain why or why not. Could a Remove() function also be defined for a singly-linked list? Explain why or why not.
Given a linked list of N nodes such that it may contain a loop. A loop here means that the last node of the link list is connected to the node at position X(1-based index). If the link list does not have any loop, X=0. Remove the loop from the linked list, if it is present, i.e. unlink the last node which is forming the loop. Example 1: Input: N = 3 value[] = {1,3,4} X = 2 Output: 1 Explanation: The link li. st looks like 1 -> 3 -> 4 ^ | |____|

Look for a point where two (singly) linked lists intersect. Return the intersection node. Remember that the intersection is defined by reference rather than value. If the kth node of the first linked list is the exact same node (by reference) as the jth node of the second linked list, then they are intersecting.
Find the existence of an intersection between two (singly) linked lists. Send back the node that intersects. Keep in mind that reference, not value, is used to define the intersection. This means that they are intersecting if the kth node of the first linked list is the exact same node (by reference) as the jth node of the second linked list.
Consider an unordered list L[0:5] = {23, 14, 98, 45, 67, 53} of data elements. Let us search for the key K = 53. Obviously, the search progresses down the list comparing key K with each of the elements in the list until it finds it as the last element in the list. In the case of searching for the key K = 110, the search progresses but falls off the list thereby deeming it to be an unsuccessful search. Write procedure code for LINEAR_SEARCH_ORDERED and UNORDERED
Beginning with a singly linked list composed of 5 nodes, draw step-by-step the process of removing index 3 from the list.
