"WebNov 3, 2016 · 1. the vector accesses its elements with iterators, which can't be a simple typedef for bool*, , which makes it slower than bitset, which doesn't provide iterators. Another thing that makes it fast is that its size is known compile-time and therefore it does no allocation with new, which is slower than stack allocation." - Bitset flip c++
