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; }
}
