Can you explain what a deque is?
A deque, or double-ended queue, is a data structure that allows insertion and deletion of elements from both ends.
How is a deque implemented in Python?
In Python, you can use the collections.deque
class, which provides an efficient way to append and pop elements from both ends.
What about in Java?
In Java, you can use the ArrayDeque
class or LinkedList
class to implement a deque, both of which support adding and removing elements from both ends.
Are there any other languages that support deques?
Yes, many languages like C++, JavaScript, and Ruby have built-in support or libraries for deques.
