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;<\/p>\n\n\n\n

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:

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
