WebOct 29, 2024 · The map::lower_bound (k) is a built-in function in C++ STL which returns an iterator pointing to the key in the container which is equivalent to k passed in the … 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
