Roads concatenation Problem Consider we have some GIS (Geo Information System) operating over some road network. Each road represented as array of two-dimensional geographical points. Road network is a set of roads. System has function called Concatenate(). This function takes raw road network and should return optimized road network. Optimization lies in concatenating roads with matching start or end points, i.e. if road AB end point matches road BC start point, then optimized network should contain concatenated road AC. Optimized network shouldn’t contain two roads which can be concatenated. Your task is to suggest set of test cases for Concatenate() function in order to make sure it works correctly. public interface IPoint { double Lat { get; } double Lon { get; } } public Road : List { } public RoadNetwork : List { } public RoadNetwork Concatenate(RoadNetwork roads);
