Answer
Deque supports insertion and removal from both ends.
A Deque (Double-Ended Queue) allows elements to be added or removed from both the front and back, providing more flexibility than a standard Queue. This is useful in scenarios like undo functionality, where you might need to add commands at the start or end. In Java, ArrayDeque is a commonly used Deque implementation.
