How do C++ STL algorithms compare to each other?

C++ STL algorithms vary in terms of performance, complexity, and use cases. For example, std::sort is generally faster than std::stable_sort because it doesn't maintain the relative order of equivalent elements.

What are the main differences between std::sort and std::stable_sort?

The main difference is that std::sort is not stable, meaning it may reorder equivalent elements, while std::stable_sort maintains their order, which can be crucial in certain applications.

Are there any performance benchmarks available for these algorithms?

Yes, performance benchmarks can vary based on the data and context, but generally, std::sort is faster for large datasets. You can find benchmarks in various C++ performance libraries or articles.

Can you explain when to use std::copy versus std::move?

Use std::copy when you want to duplicate elements, while std::move is for transferring ownership of resources, which can improve performance by avoiding unnecessary copies.
