Problem Title: "Add Two Numb You are given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list. You may assume the two numbers do not contain any leading zero, except the number 0 itself..

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…

With Head node or not? statement is: if(p->rlink == null) output << "The data doesn't exist."; O a. It is a Doubly linked list without Head node. O b. It is a Doubly linked list with Head node.

A business that sells dog food keeps information about its dog food products in a linked list.  The list is named dogFoodList.  (This means dogFoodList points to the first node in the list.)  A node in the list contains the name of the dog food (a String), a dog food ID (also a String)  and the price (a double.) a.)  Create a class for a node in the list. b.)   Use this class to write pseudocode or Java for a public method that prints the name of all dog foods in the list where the price is more than $20.00.
