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). NODEX and NODEY are neither immediate neighbors nor the end nodes of list L. a PREVIOUS X NODE X PREVIOUS X NODE Y anano (a) Before swapping g and x NODE Y NODE X Linked Lists 193 aaaaaa (b) After swapping g and x g Figure P6.10.

Write a C code that will search an int type target from a dynamic linked list. The linked list contains int type values inside each of the nodes. The “search” function will use following input-output arguments,Input: Pointer to the head of the list that you are searching Target value that you are searchingOutput: Pointer to the node that contains the target if found or, NULL if not found.

This program will use an array implementation of a linked list to keep an ascending sorted list of numbers. The input data consists of two fields: a single character and an integer value. The single character gets interpreted as one of the following: A - represents a value that is to be added to the linked listD - represents a value to be deleted from the linked listP - indicates that all values are to be printed in ascending order The character is only used to determine which process is to be executed; it should not be printed, entered into the linked list, or processed in any way. The main program should be mainly function calls. Process input data until end of file. All output should be sent to an output file and be appropriately formatted and labeled. Keep a running log of everything that is going on in the processing. Input file: A 54A -17A 32 A 81 A -30 A 18 P A 41 A 93 A 65 A 80 A 104 A -20 D 81 D 54 D -30 A 79 A 63 A 77 A –33 D 104 D -20 D 80 D 32 P

Implement a function to insert a node at the end of a doubly linked list. Explain the steps involved and analyze the time complexity of your implementation.

Suppose that you have a singly linked list with five nodes and with head reference. Then the statement head = head.next will remove the first node of the linked list? a) true  b) false
