버그도 있고 하지만...
나중에 개발자료로 쓰기 위해서 올려 두었다.. 실행시 클릭후... 방향키로 조정 할 수 있다

Djikstra's algorithm (named after its discover, E.W. Dijkstra) solves the problem of finding the shortest path from a point in a graph (the source) to a destination. It turns out that one can find the shortest paths from a given source to all points in a graph in the same time, hence this problem is sometimes called the single-source shortest paths problem.

Djikstra's algorithm을 이용해 구현해 놓은 소스이다..
아직 UI나 예외처리가 부족하다
