Gamers 27 Jan 2012 23:54 no Partisan There is some inaccuracy in the condition.In condition is writed:'The second line consist two integers x and y'. I write readln(x,y) and got WA#4. When I changed it to readln(y,x), I got AC. [8] // Problem 1401.

When I changed it to readln(y,x), I got AC. [4] // Problem 1401. Gamers 24 Oct 2005 22:52 Are you sure? Probably you write for i:=1 to x for j:=1 to y In this case you should switch x and y. Dr.Korbin Re: There is some inaccuracy in the condition.In condition is writed:'The second line consist two integers x and y'. I write readln(x,y) and got WA#4. When I changed it to readln(y,x), I got AC. [3] // Problem 1401. Gamers 16 Mar 2006 04:53 I had WA#4 for 3 times, than I replaced scanf("%d %d %d", &n, &x, &y); with scanf("%d %d %d", &n, &y, &x); and got AC! But I'm sure that there is a mistake in tests cuz I think that the first version of my program was right. :-| SuperLight No subject [2] // Problem 1401. Gamers 15 Apr 2006 16:33 I also had wa#4 before changing readln(x,y) to readln(y,x)! but now i have AC VasilySlesarev Re: No subject [1] // Problem 1401.

Gamers 19 Jun 2009 19:51 If some inaccurate statement need to be fixed, it's better to write about it to timus_support@acm.timus.ru instead of webboard. wangyin Re: There is some inaccuracy in the condition.In condition is writed:'The second line consist two integers x and y'. I write readln(x,y) and got WA#4. When I changed it to readln(y,x), I got AC. [2] // Problem 1401. Gamers 15 Nov 2006 17:40 I hadn't change x and y, but I still got AC. Maybe something wrong with your program. Nechaev Ilya (Rybinsk SAAT) Re: There is some inaccuracy in the condition.In condition is writed:'The second line consist two integers x and y'. I write readln(x,y) and got WA#4. When I changed it to readln(y,x), I got AC. [1] // Problem 1401. Gamers 15 Nov 2006 18:22 Read problem statement more careful: The second line consists of two integers x and y — those are the coordinates of the deleted cell (1 <= x, y <= 2n). X is a number of a LINE and Y — a number of a ROW. Denis Koshman Re: There is some inaccuracy in the condition.In condition is writed:'The second line consist two integers x and y'. I write readln(x,y) and got WA#4. When I changed it to readln(y,x), I got AC. // Problem 1401. Gamers 24 Jul 2008 17:50 Yep, and both LINE and ROW usually refer to something horizontal (along with Y coordinate) :) That should be rows/columns for clearer problem statement. Xysia WA #3 [6] // Problem 1401. Gamers 4 Apr 2008 14:00 OK, I had a mistake in zeroing the matrix at the beginning setup. Now I have AC.

Gamers 11 Apr 2008 21:38 Tested for input (on my computer): 3 4 5 this program gave me result: 3 3 4 4 8 8 9 9 3 2 2 4 8 7 7 9 5 2 6 6 10 10 7 11 5 5 6 1 1 10 11 11 13 13 14 0 1 18 19 19 13 12 14 14 18 18 17 19 15 12 12 16 20 17 17 21 15 15 16 16 20 20 21 21 I don't see anything wrong here. Maybe I haven't fully and correctly understood the problem? Edited by author 11.04.2008 21:42 simon Re: WA #3 [3] // Problem 1401. Gamers 19 Apr 2008 16:08 your num 0 isn't on the correct place Xysia Re: WA #3 [2] // Problem 1401. Gamers 23 Apr 2008 14:43 So you mean that I have switched rows and columns? Well, now I have changed the scanf line from (...) &a,&b) to (...) &b,&a) and now I have the following result for this test: 3 3 4 4 8 8 9 9 3 2 2 4 8 7 7 9 5 2 6 6 10 10 7 11 5 5 6 1 0 10 11 11 13 13 14 1 1 18 19 19 13 12 14 14 18 18 17 19 15 12 12 16 20 17 17 21 15 15 16 16 20 20 21 21 But I still have WA #3 :( Also, look at the other posts at the forum about this problem and you'll read that people who have exchanged rows with columns have WA #4. I have WA earlier so there must be something else wrong with my program... :( Xysia Re: WA #3 [1] // Problem 1401. Gamers 10 Jul 2008 15:01 So, could somebody give the correct solution for test: 3 4 5 ? Maybe I haven't correctly understood this problem? Denis Koshman Re: WA #3 // Problem 1401. Gamers 24 Jul 2008 17:48 3 3 4 4 8 8 9 9 3 2 2 4 8 7 7 9 5 2 6 6 10 10 7 11 5 5 6 1 0 10 11 11 13 13 14 1 1 18 19 19 13 12 14 14 18 18 17 19 15 12 12 16 20 17 17 21 15 15 16 16 20 20 21 21 x is row, y is column, I was caught by that (but AFAIK it wasn't WA3)
