Closest pair of points problem c++
WebIn c++, leave comments in code Given a set of points, the closest-pair problem is to find the two points that are nearest to each other. In the figure below, for example, points (1, 1) and (2, 0.5) are closest to each other. There are several ways to solve this problem. An intuitive approach is to compute the distances between all pairs of ...
