Given a singly linked list L, where x and y are two data elements that occupy the nodes NODEX and NODEY with PREVIOUSX as the node, which is the previous node of NODEX, write a pseudo-code to swap the date x and y in list L by manipulating the links only (data swapping is not allowed). Assume that x and y are available in the list and are neither neighbors nor the end nodes of list L. For example, given the list L shown in Figure P6.10(a), with L, NODEX, NODEY and PREVIOUSX marked on it, the swapping should yield the list shown in Figure P6.10(b).

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.
Consider a singly linked list where each node contains two fields – integerdata and node type pointer next. The head of the list and a value of the data isgiven. You have to find the node that contains the given data and delete thatnode. Data may occur at any position of the list including first or last. In caseof unavailability of the given data, you have to print a message. You have toImplement a delete operation of a singly linked list.Code in C

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.
Given a circular linked list, implement an algorithm that returns the node at the beginning 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:Output:A -> B -> C -> D -> E -> C [the same C as earlier]C

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.
Someone please solve this Question in c++ asap. Given the head of a singly linked list, return the middle node of the linked list.If there are two middle nodes, return the second middle node.The linked lists must be hard-coded, and no user input should be taken from the user.
Assume that the nodes of the singly linked lists are arranged in decreasing order of the exponents of the variable x in order to add the two polynomials.The objective is to create a fresh list of nodes that represents the addition of P1 and P2. This is done by adding the COEFF fields of nodes in lists P1 and P2 that have identical powers of variable x, and then making a new node in the resulting list P1 + P2. The key part of the technique is shown below.The start pointers of the singly linked lists that correspond to the polynomials P1 and P2 are P1 and P2, respectively. Two temporary pointers, PTR1 and PTR2, are created with starting values of P1 and P2, respectively. Make procedural code.
We assume that the nodes of the singly linked lists are organized in decreasing order of the exponents of the variable x in order to add the two polynomials.The goal is to build a fresh list of nodes to symbolize the addition of P1 and P2. This is accomplished by combining the COEFF fields of the nodes in lists P1 and P2 that have similar powers of the variable x, then adding a new node that reflects this action in the resulting list P1 + P2. The key steps of the process are presented below.Here, P1 and P2 are the single-linked lists that symbolize the polynomials P1 and P2, respectively. Furthermore, two temporary pointers named PTR1 and PTR2 have their initial values assigned to P1 and P2, respectively. Script out the process code
