So, you can use a pointer to the first element as the starting iterator, and a …
WebFor random access iterators, std::distance is O (1). Unfortunately set iterator does not support random access, so the std::distance algorithm has to iterate over the pointers to compute distance, and worst case is O (n).

WebAnd the most C++-like solution to me reads std::distance (begin (A), std::max_element (begin (A), end (A))), which works for C-style arrays as well as for STL containers; for arrays it can be reduced to std::distance (A, max_element (A, A+N)), as seen in the accepted answer. – zkoza Jan 21, 2024 at 23:20
