Consider a linked list (SLL or DLL your choice) in which, to delete anelement from the list, we simply mark that node for the deletion.Whenever the number of deleted nodes in the list exceeds the number ofnon-deleted nodes, we simply delete all nodes which were marked fordeletion. Implement the following operations for such a linked list.1. addFirst2. addLast3. delFirst4. delLast5. Delete (mark for deletion) an ith node in the list.6. display all non-deleted nodes in the list7. Size : number of non-deleted nodes in the list.8. Recall the last deleted node in the list.
Reverse a singly linked list by changing the pointers of the nodes. The datarepresented by the list should continue to remain in the same nodes of the originallist.For example, given a singly linked list START, as shown in Figure P6.9(a), the listneeds to be reversed, as shown in Figure P6.9(b), by manipulating the links alone.
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)
A singly linked list can be reversed by altering the nodes' pointers. The original list's nodes should still contain the data that the list represents.For instance, if a single linked list START is supplied, as in Figure P6.9(a), the list must be reversed using just the links, as in Figure P6.9(b).
Given a circular linked list, implement an algorithm that returns the node at thebeginning of the loop.DEFINITIONCircular linked list: A (corrupt) linked list in which a node's next pointer points to an earlier node, soas to make a loop in the linked list.EXAMPLEInput: A -> B -> C -> D -> E -> C [the same C as earlier]Output: C
You are to work to develop a linked-list processing function IsolateTargetSoloAsTail that is to process a linked list as follows. ● If target cannot be found on the given list, a new node containing target is created and added to the end (made the new tail node) of the list. ► This includes the case where the given list is empty, in which case the new tail node added is also new head node. (This is so because the only node in a 1-node list is both the head and tail node of the list.) ● If target appears only once on the given list, the target-matching node is moved to the end (made the new tail node) of the list. ► In case the target-matching node is already the tail node (of the given list), then nothing needs to be done. ● If target appears multiple times on the given list, the first target-matching node is moved to the end (made the new tail node) of the list, and all other target-matching nodes are to be deleted from the list. ►…
The MWT introduced in class has an array of pointers to children nodes in each node, and the index is used to indicate the letter on the edge. If instead we use a BST (each BST node contains a letter, a corresponding child MWT node pointer) in each MWT node, explain the advantages and disadvantages of this new “MWT” compared to the one introduced in class.
Given the following function to update a node in a standard linked list: public boolean update(Node head, int oldValue, int newValue) { if (head == null) return false; while (head != null) if (head.data == oldValue) { head.data = newValue; return true; } else head = head.next; return false; } There may be an error with the code. Answer the following: Design your own linked list of 4 nodes with different values If the code has an error, describe the issue and provide an example of calling the update function with values of your choice and show what the linked list looks like Also, show the code changes you would make to fix the error If the code does not have an error, provide an example of calling the update function with values of your choice and show what the linked list looks like For example, if your linked list was 1 -> 2 -> 3 ->…

Suppose you are given a partially-filled sorted linked list and a partially-filled unsorted linked list of the same size. Assume it is a singly linked list (no back edges).Describe the efficiency of searching for a value within each list and deleting it, including the order of such an operation.
Define an iterative function named reverse, with one linked list argument; it returns a reference to the first node in a linked (no new LN objects) with all the values in their reverse order. This method mutates the arguments list. Do not make any new LN objects. For example, for the list l1 = LN(1, LN(2, LN 3), reverse(l1) would return LN(3, LN(2, LN 1). def reverse(l: LN) -> LN:
Develop an implementation of Page that represents B-tree nodes astext files on web pages, for the purposes of indexing (building a concordance for) theweb. Use a file of search terms. Take web pages to be indexed from standard input. Tokeep control, take a command-line parameter m, and set an upper limit of 10m internalnodes (check with your system administrator before running for large m). Use an mdigit number to name your internal nodes. For example, when m is 4, your nodes namesmight be BTreeNode0000, BTreeNode0001, BTreeNode0002, and so forth. Keep pairsof strings on pages. Add a close() operation to the API, to sort and write. To test yourimplementation, ook for yourself and your friends on your university’s website.
