Implement the doubly link list with all the functions as one code. Your doubly link list performed the following operations > Insertion - Adds an element at the beginning of the list. > Deletion - Deletes an element at the beginning of the list. > Insert Last – Adds an element at the end of the list. > Delete Last - Deletes an element from the end of the list. > Insert After - Adds an element after an item of the list. > Delete - Deletes an element from the list using the key. > Display forward - Displays the complete list in a forward manner. > Display backward - Displays the complete list in a backward manne

What are the advantages and disadvantages of using a doubly linked list over a singly linked list? Give specific examples where a doubly linked list would be beneficial.
1-Let the list have a head and a tail. That is, a pointer (have a marker) to both the beginning (first Node) of the list and the last Node. What process does Tail facilitate? 2-insert(int index, int element): adds this element to the index position. For example, if index is 4, it adds this element between index 3 and 4 in the list. The size of the list has increased by one. 3-append(int elem): Adds the element to the end of the list. The size of the list has increased by one. 4-get(int index): Returns the element at the index position of the list, no change in the list. 5-remove(int index): Returns the element at the index position of the list. This element is removed from the list and the list size is reduced by one. 6-findMin(): returns the index of the smallest number in the list. 7-findMax(): returns the index of the largest number in the list. 8-search(int elem): searches elem in the list. It returns -1 when you can't find elem's index when you find it. 9-ToArray(): Return an…
C++ Program This assignment consists of 2 parts. 1. Append Process: Create a Linked List that will store integers. Using the provided getData() method (See below), append 20 numbers to the Linked List. After loaded, display the data. Start with the Head of the list. Prompt for user to proceed. 2. Insert Process: Delete the contents of the Linked List in part 1. Using the provided getData() method, insert 20 numbers into the list and place them in the list in numerical order (1..X). Do not allow duplicates to be in the list. Hint: Do not allow a duplicate to count as a member of the 20. After loaded, display the data per line in order, starting with the Head of the list. Display the content with a leading increasing number 1- 20. i.e. 11 13 14 20 The result should be a naturally sorted. Do not use the STL list container for this exercise. Use the features described in section - Linked List Operations. Using a Class to manage the linked list as shown in section is…
Create a C++ linked list class for integers. Appending, inserting, and removing nodes should be class member functions. Add a list destructor. Drive the class. Add a print function to your linked list class. Display all linked list values. Start with an empty list, add elements, and print the list to test the class.
1. Write a function to search and return the node, in a single linked list, having a given value v node * search (int v) 2. Write a function to delete the node after the one returned by the search in question 1 void delete_after (node *p) 3. Write the main method and give screen shot of the execution
Make a data structure that enables the access and delete actions. If the item isn't already on the data structure, the access action adds it. The object with the least recent access is deleted and returned by the remove operation. Hint: Maintain references to the first and last nodes as well as the items' order of access in a doubly linked list. Use a symbol table where the keys represent the items and the values the links in the list. Remove the element from the linked list after accessing it, then reintroduce it at the start. When you eliminate an element, do both the symbol table and end deletions.
write a function that add any item in a linked list after the item X, if the item X is not found in the linked list don't add the item.
Task 13: The function below should insert a value as the head of a given UNORDERED linked list. Be careful to first search for the given value. The value is inserted only if it does not exist in the list. If the value exists, the function does nothing. Use Linked list implementation of Task 1 to make this function run. Write down the code of insert function run the code, take snap shot and paste it in your document. struct Node{ int data; Node* next; }; The function prototype is given. Implement the function. void insert(Node* &head, int value);

def print_categories(main_list): for i in all_categories: main_list = all_categories.split() print(i,":",all_categories[i]) return "" """ Given a list of lists, for each list stored in main_list, output its contents as follows: f"{index of category}. {item[0]} - {item[1]}%". note that indexing must start at 1 for the first item, not 0, which is first item's actual index in main_list. If `main_list` is empty, the function prints "There are no categories." Returns the number of categories.
Read each of the descriptions carefully. Decide whether the description applies to a List, a Dictionary, both structu The structure is mutable, that is, the structure itself can be changed by adding, removing, or rearranging the elements in the structure. v The elements in the structure are "unordered The clements in the strurture are ydered'. v The structure works exactly ilke array types delined in ather languages. A. Dictionary v Flements in the structure are indexed. B. Both v To add an element, use either the insert or append method. C. Neither v To remave an element, use the pop medhod. D.List Access a singe element of the structure by referring to its position in the structure. v Access a sirngle clement of the structure by referring to an index value. All elements in the structure must share a single data type (integer, fiaat, string, etr.
The remove method of the reference-based list implementation takes O(N) time because it needs to shift elements after the remove operation. True False
