WGU C949 Data Structures and Algorithms I Exam (Latest 2023/ 2024 Update) Questions and Verified Answers| 100% Correct| Grade A Q: Give a coded example on how to create a 3 chained linked list of nodes. Answer: - Node head = new Node(1); head.Next = new Node(2); head.Next.Next = new Node(3); Q: A list where we start at the first node and follow the chain of nodes iterating over each until we get to the end Answer: Singly Linked List Q: A list that builds on the singly linked list by adding reverse iteration. Answer: Dou- bly Linked List Q: Give a coded example on how to create a doubly linked list Answer: Node node1 = new Node(1); Node node2 = new Node(2); Node node3 = new Node(3); node1.Next = node2; node2.Previous = node1; node2.Next = node3; node3.Previous = node2; Q: The first and last nodes of a doubly linked list should have a value of Answer: null Q: Adds a value to the beginning of the list Answer: AddHead Q: Adds a value at the end of the linked list Answer: AddTail Q: Finds the first node whose value equals the provided argument Answer: Find Q: Returns true if the specified value exists in the list, false otherwise Answer: Con- tains Q: Removes the first node on the list whose value is equal to the argument Answer: - Remove Q: A doubly linked list where the values are inserted and sorted in order Answer: Sort- ed List Q: Adds the specified item to the linked list in the sort order of the item type Answer: Add Q: A way of organizing, storing, and performing operations on data Answer: Data Structure Q: A data structure that stores subitems, with a name associated with each subitem. Answer: record Q: A data structure that stores an ordered list of items, with each item is directly accessible by a positional index. Answer: Array Q: A data structure that stores ordered list of items in nodes, where each node stores data and has a pointer to the next node.
