WA 49 Hint	Dmitriy	1216. Two Pawns and One King	27 Dec 2020 00:49	1
WA 49 Hint Dmitriy 27 Dec 2020 00:49 If you decide not to repeat my mistake, then the 49th check is that the king must bypass the black pawn in order to catch up with the white one, I will not talk further, but just give you an example: 8 a3 d7 e6 Answer:BLACK WINS

It makes me more considerate and ..trains my patience...

TO ADMINS!!! - Importatnt statement missing! Armen Tsirunyan 22 Dec 2008 02:14 Dear Admins, don't you think that it would be prudent to state(or at least give a little hint), that WHITE IS TO MOVE FIRST?!!! Or is it so self-evident?! Thank you.

WA#6 :( RockBeat 6 Jan 2007 15:46 My prog passes all 307 tests from the forum and gets WA6, help me please... ) Re: WA#6 :( Armen Tsirunyan 22 Dec 2008 03:04 I had the same problem. I was inputting data as follows. char x, y; cin>>x>>y; WhitePawn.x = x-'a'+1; WhitePawn.y = y-'0'; What I should have done was char x; int y; cin>>x>>y; WhitePawn.x = x-'a'+1; WhitePawn.y = y; Got the point? That's why your prog passes all f*illion tests on this forum- they all have n=8. GoodLuck!

i got ac without checking cases but searching frost 30 Oct 2006 17:58 i think it's much easier and faster. Re: i got ac without checking cases but searching Vedernikoff Sergey (HSE: EconomicsForever!) 5 Jul 2008 18:54 Yes, I did the same thing. In this case it is much simpler not to forget something...

finally i got ac...... yuhch 12 Sep 2007 08:14 i changed my algorithm from checking cases to searching with memorizing, but always get wa on test 7. after one day's struggle, i'm nearly crazy... at last i found my reading part has a mistake that i read the data like this: scanf("%s", tmp); p[0] = tmp[0] - 'a'; p[1] = tmp[1] - '1'; but when N is greater than 9, p[1] may have 2 digits...... i hope no one will make SUCH a SILLY mistake like me, especially spending one day on it...

To Admins: Please put this detail into problem's description: (+) Michael Rybak (accepted@ukr.net) 29 Oct 2004 07:43 It is nothing said about the following situation: 6 a2 a3 f1 I.e., whether a white pawn can jump over a black pawn from 2nd row on the 4th. Nothing is said in the problem statement, but a program which would output "WHITE WINS" for this test case gets WA on test 3. Please complete the problem description with this remark (or excuse me, if I didn't notice how to conclude an unambiguous rule for this case) And I also sent a test to yakovlev@metronome.ru, which possibly should be added to the test set, because my 2 programs, outputing different answers for this test case, both get AC.

K..... White pawn can jump from c2 to c4. Black pawn can't block it. Then WHITE player WINs the game. Edited by author 27.10.2004 00:23 Edited by author 27.10.2004 00:24 You're wrong. Read problem definition carefully (+) Dmitry 'Diman_YES' Kovalioff 27 Oct 2004 13:27 "Just after the white pawn makes a move from x2 to x4, the black pawn may beat the white pawn en passant, moving from y4 to x3, if y is a vertical line, neighboring to the x-vertical."

Hints (+) Dmitry 'Diman_YES' Kovalioff 23 Dec 2002 08:41 I've got AC many weeks ago but a lot of people cann't do it. The task is not so hard as one may think, but it needs this: 1) Before coding you must find out all the tricks on paper (and there are a lot of tricks) 2) Your program must have a good structure 3) You must code it very accurate, because it'll be very hard to find a mistake later So, hints: I. If your program works on 88 board it'll work on every board from 66 to 2626 II. My program's structure is following: 1) if black pawn (BP) stops white pawn (WP) -> BLACK WINS 2) if BP bites WP -> BLACK WINS 3) if WP bites BP (on first move, of course) and saves itself (runs away from square and black king (BK) can't catch it after that) -> WHITE WINS 4) if BK is in square (it can catch WP) and BP cann't prevent it standing initially on BK's way -> BLACK WINS 5) if BP trasforms into other figuge (I considered that it transforms into queen) and bites WP -> BLACK WINS otherwise -> WHITE WINS III. Here are some tests for you on every case described above: 1) 8 a2 a7 h1 BLACK WINS 8 a6 a5 h1 WHITE WINS 2) 8 a3 b6 h1 BLACK WINS 8 a6 b6 h1 WHITE WINS 3) 8 d5 c6 f5 WHITE WINS 8 d5 c6 a5 WHITE WINS 4) 8 b4 d5 e4 WHITE WINS 8 b3 h7 f3 BLACK WINS 8 b2 h7 g2 WHITE WINS 5) 8 b4 b3 h2 BLACK WINS 8 b5 b3 h2 WHITE WINS 8 b5 b2 b3 WHITE WINS 8 a4 g3 h8 BLACK WINS 8 a4 g3 g2 WHITE WINS 8 a4 h3 h8 BLACK WINS 8 a4 h3 g2 WHITE WINS I hope if you program passes all theese tests it gets AC.

Help ! What dose this sentence mean ? XueMao 23 Nov 2002 17:54 White pawn is allowed to move to the fourth horizontal from the second, and black pawn is allowed to move to the (N-3)-rd horizontal row from the (N-1)-st. Could anyone explan it more clearly and fully ? Thanks a lot !!! Re: Help ! What dose this sentence mean ? Илья Гофман (Ilya Gofman) 23 Nov 2002 18:38 > White pawn is allowed to move to the fourth horizontal from the > second, and black pawn is allowed to move to the (N-3)-rd horizontal > row from the (N-1)-st. > > Could anyone explan it more clearly and fully ? Thanks a lot !!! It means that according to the rules of chess the pawn may(and may not) move in the first time by 2 fields ahead, not by one as usual. It is olny the first move, no more. Understand now? Good Luck.
I've got AC!!! Questions?	Dmitry 'Diman_YES' Kovalioff	1216. Two Pawns and One King	11 Nov 2002 13:07	6
I've got AC!!! Questions? Dmitry 'Diman_YES' Kovalioff 10 Nov 2002 13:09 IMHO, this task is quite simple - I've got AC after 2 sumbits. The main idea is to describe all variants on paper (there are not so many variants as it seems) and ACCURATELY code it. I've done it after 1.5 hours. Congratulations to Leonid Volkov - the task is rather good. P.S.

Leonid Volkov help me please. Danilchenko Anton 5 Nov 2002 11:19 On all your tests, which I have found, my program works correctly, but alltimes I have got WA. Why? What about this test (8x8): WP: e5 BP: d6 BK: c6 WHITE WINS!!!!! but: WP: e4 BP: d5 BK: c5 BLACK WINS!!!!! May BK stand under check in initial position? Please give me tests on all cases, which you have accounted in your program. Re: Leonid Volkov help me please. Leonid Volkov 6 Nov 2002 16:48 Tests are not a subject to be published, as you know :-) You may send me your program, and I'll try to find out, what's wrong.
