What is double list codehs?

Double List in CodeHS is a data structure that allows you to store and manipulate a sequence of values. Each value in the list is connected to two other values, forming a bidirectional link between adjacent nodes.

The Double List class in CodeHS has several built-in methods that allow you to add, remove, and modify elements in the list. Some of the most commonly used methods include:

• append: Adds a new element to the end of the list.
• insert: Inserts a new element at a specific position in the list.
• remove: Removes an element from the list.
• pop: Removes and returns the element at a specified position in the list.
• index: Returns the position of an element in the list.
• count: Returns the number of occurrences of a specified element in the list.
• clear: Removes all elements from the list.

Double List can be very useful in scenarios where you need to maintain a sequence of values and access them in a particular order. Some examples of use cases for Double List include implementing a deck of cards, managing a playlist of songs, or storing a history of visited web pages.
