[Octave-bug-tracker] [bug #63962] perms - Performance - Usage of native C++ algorithm helpful

[Arun Giridhar]

Follow-up Comment #2, bug #63962 (project octave):

Right, I see that std::next_permutation does not generate repetitions, so it
won't spike memory usage:
https://en.cppreference.com/w/cpp/algorithm/next_permutation 

There's a note there that its behavior changes in C++20 (becomes a constexpr)
but that should not be a concern.

Post your code when ready.
