WebB-trees are frequently implemented in C++ as templates, allowing for flexible customization for various data and application types. The balanced tree structure of the B-tree data structure makes it ideal for efficient data searching, insertion, and deletion. The order of the tree, also known as the maximum number of child nodes allowed, is ... Weberasing multiple items using the range form is log (c.size ()) + std::distance (first, last) (i.e. - log of the set's size + the number of elements deleted). - with fixed set's size is scales exactly as O (n) where n is number of elements deleted, which is what you get from deleting them one by one. – Cthulhu Mar 3, 2014 at 9:53
