C++ stl binary search
Web1. Binary Search in STL. In C++, STL library has std::binary_search function defined in the header “algorithm”. It takes the iterators to the starting and ending positions of a sorted sequence and returns true if the target value is found; otherwise, returns false. This search operation takes O (log (n)) time and is very efficient even for ...
