16:  ##.#.#.#.#.#.#.#.#.#.#.#.#.#.###.
第15，16行之间不能连通！

I am get WA on test 4 too!
test 4 is wrong!

我知道TEST 4怎么WA的了！
有几点要归纳出来：
1：
ural 有保留字：
Following words are reserved. For Pascal: as
class
dispose
except
exit
exports
 false
finalization
finally
initialization
is
library
 new
on
property
raise
true
 try
我就使用了"try"这个保留字，结果就编译错误了。
2：
第四个数据的底15，16行不能连通！
所以：要从点（1，1）与点（N，N）分别搜索！（我是广搜）
如果只从点（1，1）开始搜，结果为：5760。
如果只从点（N，N）开始搜，结果为：6624。
两者之和正好是正确答案：12384 ！

希望我写的这些对你有用！

Thank you very much!You are so clever!

....
竟然可以打中文的....

Thanks a million!!!

可以中文？？？

上面的几位聪明的中国大牛同胞，看没看见下面的Rules?明确写着“Messages should be written in English.(消息必须用英文写)”，请遵守规则，谢谢。
-------
To my clever Chinese friends above, didb't you see the Rules below? It says clearly that "Messages should be written in English." Please obey that. Thanks.

the thing is, there doesn't have to be a path from 1,1 to n,n, so you have to check both sides.

i got WA at test 4 ,too!

thank you!!

why cant't discussion be written in chinese or russia??

# Messages should NOT contain source code (especially correct solutions). why??  i think source code indeed may cause cheat,but someone who always gets WA really need them to improve
