发现填充在网格有一个圈;填写该地区

您需要拆分所有你白 （未填充） 的正方形成台套正方形彼此相邻。从任何白色的正方形出发，向集，添加所有其未填充的相邻方块，继续做下去，直到你已经包含所有的方块。

一旦你有了这些设置，你将有"圈"（如您命名它） 如果有非空集不包含任何边框广场。然后要填补这些集您只需更改每个成员为蓝色的颜色。

如果你有从前面的步骤，集添加另一块砖，你只是需要考虑的集，攻城掠地变态sf，包括受影响的广场，看看是否它已被划分为两个集时，是否这些新设置五月是一个"圆"。

You need to split all of your white (unfilled) squares into sets of squares adjacent to each other. Start with any white square, add all of its unfilled adjacent squares to the set, and keep doing it until you've included all of the squares.

Once you have those sets, you will have a "circle" (as you named it) if there are non-empty sets that do not contain any border squares. Then to fill these sets you just change the color of each member to blue.

If you have the sets from the previous step, when you add another brick you just need to consider the set that included the affected square to see if it has been split into two sets and whether either of these new sets may be a "circle".
