WebSep 27, 2024 · In C++ the Standard Template Library (STL) provides the function lower_bound (), which can be used as shown in the following example [2].

WebJan 10, 2024 · The lower_bound () method in C++ is used to return an iterator pointing to the first element in the range [first, last) which has a value not less than val. This means that the function returns an iterator pointing to the next smallest … WebBasically lower_bound is a binary search looking for the specified "gap", the one with a lesser element on the left and a not-lesser element on the right. Then you return an iterator to the element on the right of that gap. Regular binary search is looking for an element, not a "gap", – Steve Jessop Jun 22, 2011 at 16:58 1
