What are the new features in C++17's standard algorithms?

C++17 introduced several enhancements to the standard algorithms, including new algorithms like std::reduce, std::for_each_n, and improvements to existing ones.

Can you explain how std::reduce works?

Certainly! std::reduce is used to perform a reduction operation on a range of elements, combining them into a single value using a binary operation.

What is the difference between std::reduce and std::accumulate?

The main difference is that std::reduce can be parallelized, while std::accumulate is sequential. This makes std::reduce potentially faster for large datasets.

Are there any performance considerations I should be aware of?

Yes, while std::reduce can be faster due to parallel execution, it may introduce overhead for small datasets. Always benchmark for your specific use case.
