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 WebFrom cppreference.com < cpp algorithmcpp algorithm C++

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 parameter.

WebThe comparisons are performed using either operator< for the first version, or comp for the second; An element is the smallest if no other element compares less than it. If more than one element fulfills this condition, the iterator returned points to the first of such elements. The behavior of this function template is equivalent to: 1 2 3 4 5 6 7
