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. Gamers 24 Oct 2005 16:03

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.

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. :-|

I also had wa#4 before changing readln(x,y) to readln(y,x)!
but now i have AC

The same

If some inaccurate statement need to be fixed, it's better to write about it to timus_support@acm.timus.ru instead of webboard.

I hadn't change x and y,
but I still got AC.
Maybe something wrong with your program.

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.

Yep, and both LINE and ROW usually refer to something horizontal (along with Y coordinate) :) That should be rows/columns for clearer problem statement.
