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 Webconstexpr ForwardIt lower_bound( ForwardIt first, ForwardIt last, const T& value, Compare comp ); (since C++20) Returns an iterator pointing to the first element in the range [first, …

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 WebThe function optimizes the number of comparisons performed by comparing non-consecutive elements of the sorted range, which is specially efficient for random-access iterators. Unlike lower_bound, the value pointed by the iterator returned by this function cannot be equivalent to val, only greater.

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]. There’s also the function binary_search (), which returns a boolean whether the target exists in the sorted array or not but not its position [1].
