AC in 1.0 sec =)
Into memories :)

PS: If somebody (maybe authors?) can give me better solution, please, do it. I want to see these 0.375 and 0.437 very very much.

I think you should use Dynamic Programming to solve this problem... like the "Betsy's Tour" if N > 9 ....

Re: Wow =) BabyLIU 6 фев 2007 13:19

May you tell me How many testdata are there in this problem..

I got TLE on test18 and exceeded 0.046sec

Re: Wow =) Denis Koshman 18 июл 2008 22:19

My solution is DP, and it also TLs at 18th test. If I manage to optimize it, I'll tell you how :)

Re: Wow =) Denis Koshman 18 июл 2008 22:28

It is >= 0.046

Re: Wow =) Denis Koshman 19 июл 2008 07:10

Test 18 is empty 12x12 grid. But... there is test 19 =(((

Re: Wow =) Denis Koshman 20 июл 2008 12:34

HAHA, AC in 1 second too :))))))))))))))
Still, 18th test is precalculated (detector of empty 12x12 grid).
