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).

} (1 of 3 parts) Consider the function below that is given the head and tail pointers to a double linked list. bool patronum (Node ✶h, Node * t) { bool c = true; if (t nullptr) return true; Node* p = t; while (p != h) { Node* j = p; Node* r = p->prev; EXAM for (Node* r = p->prev; r != nullptr; r = r->prev) { if (j->value > r->value) { c = false; j = r; } swap(p->value, j->value); p = p->prev; return c;
Suppose a node of a linked list is defined as follows in your program: typedef struct{ int data; struct Node* link; } Node; Write the definition of a function, printOdd(), which displays all the odd numbers of a linked list. What will be the time complexity of printOdd()? Express the time complexity in terms of Big-O notation.
1. Suppose you have already developed an SLL ADT. You have to search a specificelement of the linked list. If you find the element in the list then you have to swapits previous node with its next node. Otherwise, simply print the message “Datanot found”. Now write a function in your SLL ADT with this functionality.

Create an implementation of singly linked list using classes with minimum 5 nodes (spectre, togusa, yuri, siren, shepherd) in Python with the following capabilities/functions: Traverse - print out all data from the linked list Insert - generate a node and attach to an existing linked list Search - find an item (data) from the linked list and return the node Remove - remove a node from the linked list
We have a list. For example [2,4,6,6,8,2,12,54,15]. Without repeating the elements in the list a new list that does not repeat its elements by creating and using the function that writes Create.

write a program to find second maximum node in circular link list. First you design structure of circular linked list then perform these functionality.
Given a list of ‘n’ distinct elements, the task is to find all elements in the list which have at-least two greater elements than themselves. Maintain two separate list, one holding all such greater elements and the other list containing the rest of the elements in the same order. If the number of elements in the input list is less than or equal to 2 then the first list should contain ‘0’ and second list should contain all the input elements in the list.
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
