The Linked List Iterator Described in the Textbook Maintains a Reference

question 3

Multiple Choice

The linked list iterator described in the textbook maintains a reference to the last visited node, called position, and a reference to the last node before that, called previous.Which of the following statements is NOT correct regarding advancing this iterator?

• A)If another node exists, when the iterator is to be advanced, the position reference must be updated to position.next.
• B)If the iterator currently points before the first element of the list, when the iterator is to be advanced, position must be set to point to the first node in the linked list.
• C)If another node exists, when the iterator is to be advanced, the previous reference must be updated to point to the current location of the iterator
• D)If the iterator currently points before the first element of the list, when the iterator is to be advanced, the position reference must be set to position.next and the previous reference must be set to point to the first node in the linked list.

Linear Inequalities

Equations that involve inequalities (like <, ≤, >, ≥) between variables that, when graphed, form lines that split the plane into half-spaces.

System

A collection of rules or methods that dictate how something is executed; a structured plan or approach.

Graph

A visual representation of data or mathematical functions, typically drawn on a coordinate plane, showing the relationship between two or more variables.

Linear Inequalities

Mathematical statements involving linear expressions subject to inequality relationships, like greater than or less than.
