( "C # 프로그램"모드에서 LINQPad를 통해;)
골프가 갈 때까지 Equitable Stroke Control을 적용해야하지만 이것이 C # ( 내가 LINQPad이지만 내 C # 응용 프로그램을 작동시키는 모든 상용구를 원하는 사람은 누구입니까?) 에서 내 접근 방식입니다 .
그리드 정의는 가변적이며 여러 개의 수직 파이프와 전체 구조의 높이를 가지며 시드를 전달하여 반복적으로 무작위입니다 ( PipeGrid생성자 참조 ).
어느 방향 으로든 가능하다면 객체가 어떤 방향으로 흐를 지에 대한 명확한 대답이 없다면, 많은 옵션에서 행동을 지정할 수 있습니다 ( SolveBehavior열거 / PipeSolver생성자 참조 ).
수직 시작은 정의 가능합니다 (참조 PipeSolver.Solve).
수평 파이프는 항상 두 개의 인접한 수직 파이프 사이에 있다고 가정했습니다. 즉, 수평 파이프는 수평 파이프 를 우회 할 수 없습니다.

내 평범한 오래된 텍스트 출력을 두려워하는 것은이 인기 컨텍스트에 대한 약간 단조로운 수 있습니다, 나는 확장 버전까지 제공 도 이미지로 촬영 경로를 그립니다합니다. 나는 그것을 끔찍한 도로 네트워크를 통해 운전하고 바닥에 가려고하지만 자동차로 모델링했지만 세계에서 가장 최악의 GPS를 사용하여 모든 교차점에서 회전해야합니다.
보너스로, '턴'을 더 명확하게 볼 수 있습니다.
즐기세요 -vroom vroom !!
