I think it's an easy recursive problem,
but I have got WA for several times.

Could anyone give me some test data
thx

I try to solve p10713 but get WA

My method is go northwest/northeast/southwest/southeast first,and
then go north/south/east/west.
So there are two instructions at most .

Is there something wrong?
Plz help me

I try to use Dijkstra's algorithms to solve this problem
but it's too slow...............

Could someone help me or give me some hint
THX.

Could anyone give me a hint how to solve it efficient

I have a question.
How to know how many kinds of "basic rectangle" are and how to find them.
