In a double-ended queue (deque), which operations can be performed at both ends?
Step 1: Understand what a double-ended queue (deque) is. It is a data structure that allows adding and removing elements from both the front and the back.
Step 2: Learn about the operations that can be performed on a deque. These include 'enqueue' (adding an element) and 'dequeue' (removing an element).
Step 3: Recognize that in a deque, you can perform 'enqueue' and 'dequeue' operations at both the front and the back. This means you can add or remove items from either end.
Step 4: Compare this with a standard queue, which only allows adding to the back and removing from the front. A deque is more flexible because of its ability to operate on both ends.
