'For example, consider the route of a subway station
I want to go from a station called A to a station called U, but there are multiple routes from A station to U station. It is easy to think of the shortest route to U station at that time, but I do not know the program to investigate the route to a few stations on the way. Does anyone know how to write a program that does not change the goal at U Station, but makes 4 or 6 variable such as 4 stations ahead or 6 stations ahead?
