Actually, once you understand this algorithm, I think the best place to go next would be to change it to a breadth-first traversal. The intuition here is that a maze is an undirected graph, and this algorithm constructs the maze by traversing that graph in depth-first order. This is d...

参照渡し (call by reference) とは、変数のメモリ番地を渡す渡し方です。これにより、あたかも変数が共有されたような状態になります。 リスト 4 をご覧ください。これは list3 と同じコードですが、もし Ruby が参照渡しだったとしたら、最後の行の出力結果が list3 とは異なるはずです。 list4. もし Ruby が参照渡しだったとした場合 def foo(a, b) # a, b を「仮引数」という a += 1 b += 2 # a と b を変更する end x = 10 y = 20 foo(x, y) # x, y を「実引...
