What are the performance characteristics of a deque?
A deque, or double-ended queue, allows insertion and deletion of elements from both ends. Its performance is generally O(1) for these operations.
How does a deque compare to a stack and a queue in terms of performance?
While a stack and a queue allow operations at one end, a deque provides more flexibility. Both stacks and queues have O(1) performance for their respective operations, but deques can perform O(1) operations at both ends.
Are there any specific use cases where a deque is preferred over other data structures?
Yes, deques are ideal for scenarios like implementing a sliding window algorithm, where you need to access elements from both ends efficiently.
What programming languages support deque data structures?
Most modern programming languages, including Python, C++, and Java, have built-in support for deques in their standard libraries.
