Permutations

Explore how to apply std::prev_permutation and std::next_permutation algorithms to generate previous and next permutations of a range in C++. Understand the importance of bidirectional iterators and the requirement for custom sorting criteria to follow strict weak ordering to avoid undefined behavior.

We'll cover the following...

std::prev_permutation and std::next_permutation return the previous smaller or next bigger permutation of the newly ordered range. If a smaller or bigger ...
