- How to crate a circular linked list in c++ where it should have following functions supported: Create a playlist using multiple songs. Add songs to the playlist. Remove a song from the playlist. Play songs in a loop (for this activity, we will print all the songs once) and should allow for common operations on a playlist such as: next, previous, play all songs,insert and remove.Question : Write a c++ program which creates a Linked List having maximum sum out of two Sorted Linked Lists. Use this : LinkedList finalMaxSumList(LinkedList List1, LinkedList List2); For eg: You have two sorted linked lists, create a linked list that contains data with maximum sum. The resulting list with maximum sum will contain nodes with data from both input sorted lists. While creating the resulting list with maximum sum, we may switch to the other input list only at the point of intersection (which mean the two nodes with the same value in the lists). You are only allowed to use O(1) extra space. Note: You have to returned Linked List which contain finalMaxSumList and you are not allowed to change in data type and prototype of the Function. Input:List1 = 1->3->30->90->120->240->511List2 = 0->3->12->32->90->125->240->249 Returned LinkedList: Following is resulting linked list out of two sorted listsResultingList =…Python Pandas: How do I split a list into columns?

- Old MathJax webview Old MathJax webview In Java Some methods of the singly linked list listed below can be implemented efficiently (in different respects) (as opposed to an array or a doubly linked list), others not necessarily which are they and why? b. Implement a function to add an element before the first element. c. Implement a function to add an item after the last one element. d. Implement a function to output an element of the list. e. Implement a function to output the entire list. f. Implement a function to output the number of elements. G. Implement a function to delete an item. H. Implement a function to clear the entire list. I. Implement functionality to search for one or more students by first name, last name, matriculation number or course of study. J. Implement functionality to sort the records of the student, matriculation number and course according to two self-selected sorting methods.Write C++ code to display all even numbers in the a doubly linked list pointed to by Dlist. Use while loop to scan all nodes from the start to the end. (Each node has three fields: a data field that contains the information, and right and left fields contain pointers to nodes on either side. Ex. p->left represents the address of the node to the left of node p) (any number of nodes in the linked list) Dlist 4 3 8 HIIN 7 1Please Use C language. 1. In most personal computers, the largest integer is 32,767 and the largest long integer is 2,147,483,647. Some applications, such as the national debt, may require an unbounded integer. One way to store and manipulate integers of unlimited size is by using a linked list. Each digit is stored in a node of the list. For example, the figure below shows how we could store a five-digit number in a linked list.
- Create a program in C++ using a character linked list. It will insert the letters into the list alphabetically. Ask the user to enter a word. Then, enter the word into the list. Then, print out what is in the list, and clear it out. example: enters: apple prints: aelpp You can do this by writing your own linked list (extra credit), or using the STL list class. -- if you are using the STL list class, do not use the “sort” function.By using the linked list class provided (linkedList.h), write a C++ code to; Ask the user to enter five characters to be stored in the list. Build a linked list (List 1) forward using the five characters. Build another linked list (List 2) backward using the five characters. Print the characters in List 1. Print the characters in List 2. Ask the user to enter an item to be deleted. Print the list after deleting the item. Ask the user to enter an item to be searched. Print the message if the item was found in the list. Sample Output: Enter five characters to be stored in the linked lists: a b c d e List 1: a b c d e List 2: e d c b a Enter item to be deleted: b Lists after deleting b: a c d e e d c a Enter Item to be snatched: a a found in List 1. a found in List 2.you are going to write a program in C++ that implements a doubly linked list. The data must be read from the files, and you can put the file names in your program. Letters.txt contains 26 English Letters: A B C D *** N Sequence.txt contains a list of numbers. 3,-3,19,-19,18,1,-2,3,-18,17,1,-3,-13,14 You need to 1. Create a doubly linked list by reading the 26 letters from Letters.txt. 2. Sequence.txt file contains a sequence of relative letter positions. The initial position is at the beginning of the list which is 'A'. The first number in the sequence is '3'. So, the current position will move forward for three steps. Then the first letter to output is 'D' and now the current position is at 'D' as well. The second number in the sequence is '-3'. Then the second letter to output is the third element backward from the current position which is 'A'. You | need to output all letters indicated in sequence.txt Your need to 1.
