What are the differences between deque and list in various programming languages?

What are the main differences between deque and list in Python?

In Python, a list is a dynamic array, while a deque (double-ended queue) allows for fast appends and pops from both ends.

How does this compare to Java?

In Java, ArrayList is similar to Python's list, while LinkedList can function as a deque, allowing efficient insertions and deletions.

Are there any performance differences I should be aware of?

Yes, lists are generally faster for indexed access, while deques are better for operations at both ends, especially with large datasets.

What about in C++?

In C++, std::vector is like a list, while std::deque provides similar functionality to Python's deque, optimized for both ends.
