return value in std::copy documentation seems to be wrong

[Johannes Choo]

Hi all,

I'm a beginner with C++, but the documentation for std::copy seems to be
mistaken in its documented return value (
https://gcc.gnu.org/onlinedocs/libstdc++/latest-doxygen/a01486.html#ga894f503412130680dc19c87af289f4f4
). It reads,

Returns: result + (first - last)

where the copy function signature is std::copy(first, last, result).

Shouldn't it be

result + (last - first) ?

Bests,
Johannes
