pls help. i think i don't understand how it works.

say 52 cards, input: c1,c2... c52
then non-dealer gets c51, c49, ... c1.
and dealer gets c52, c50, ... c2.
then non-dealer starts with c51, dealer starts to play with c52. so on.

let's do it by example (simplified):
non-dealer (3 cards): 2 J 2 3
dealer (3 cards): 2 3 4 5
so 2->2->J, then dealer needs to cover by 3.
so will become
non-dealer: 2 3
dealer: 4 5 2 2 J 3,
is it? and the dealer next plays 4?

that's my interpretation, and i don't know why i can't even product the sample output "1 44" from the sample input.

think about this situation...

no-dealer : 2 Q 4 3...
dealer : 3 K 5 2 ...

then begin ...

2 -> 3 -> Q ...and now dealer should put 2 cards...
but when dealer put one card...we find it is "K"...
then dealer need not put the second card...
and no-dealer then should put three cards....

till any player has no cards to put...
and the other will win the game...

i understand that. it'll be reversed when 'K' is put. but still cannot work out the sample. so what else is missing?

Sorry....I made a mistake..

if ...

non-dealer 2 J 2 3
dealer 2 3 2 4

than 2-> 2-> J ...then dealer cover by 3 ..
and then "non-dealer" take the heap...

non-dealer 2 3 2 2 J 3
dealer 2 4

then non-dealer put 2 ...

162 Sample Inputs

Post by Aggag » Sat Aug 31, 2002 11:04 pm

Does anyone have some sample inputs for the "Beggar My Neighbour" problem (162). I have got the provided sample input right but still get WA from the judge over and over again. Its may be that i am missing something that isnt included in the sample input. Thanx alot in advance.

FInally got an ACC!!! I've made a very very minor glitch......

P.S. My program fails in cases like this:
DQ H2 H4 D4 D5 HK D3 D4 H3 D5 D7 S3 S2
D2 H2 H4 D3 D5 H6 D3 D4 H3 D5 D7 S3 S2
D2 H2 H4 D3 D5 H6 D3 D4 H3 D5 D7 S3 S2
D2 H2 H4 D3 D5 H6 D3 D4 H3 D5 D7 ST S2

I can't understand why I get WA. Are there any special cases I should care for? Any sample tests? Which input format is correct:

It came out that I misunderstood the problem. A player looses not when he has no cards, but when he has no cards _and_ he has to make a move.

My TLE app can solve about 250000 inputs in 10 seconds on my Athlon 2200. I can scarcely believe my app is too slow.
Unfortunately, it is possible to have a cycle in the game. One such a cycle is:

Code: Select all

ST S8 C6 C6 ST HT D6 D6 DK H2 D6 D5 D2 
H3 C8 H8 D5 H3 HT CJ S5 D2 H7 H7 SK ST 
D3 D9 H3 S9 C3 CT C6 S8 S7 H5 H5 S3 ST 
C7 H2 H2 D6 D5 H5 D8 C8 C5 D4 H3 S8 D9

Can someone with an AC app tell me whether their app gives a result?

Also, can someone with an AC app send me their (Windows) exe so I can test against my app?

Infine loops

Post by danielrocha » Mon Apr 19, 2004 9:09 pm

I don't think you should really worry about that input. I ran it on my AC program and it also locked (circular loop). There were two inputs that I tried before getting the program accepted:

Code: Select all
