Answer 2

A deque (pronounced “deck”) stands for double ended queue. It functions like a deck of cards, where you can add / remove elements to both the beginning and the end of the list with the same speed as appending an element to the end of a normal array.

One disadvantage is that it is not indexed, meaning you must scan through the deque to find an element. This is unlike an array where you can directly access an element at position 3 by doing A[2] (remember arrays start counting from 0).
