Todor Tsonkov Test 8 [4] // Problem 1506. Columns of Numbers 30 Oct 2006 22:17

Is there something wrong with test no.8, because I get Wa there and my algo, I suppose, is right ?

I think test 8 is correct because I got AC. My solution in Java:

Numbers in the range from 0 to 999. There can be a problem with 0.

I read numbers like strings, thats why problems with values of numbers is not awaited.
But anyway I have a problem with test #8. Hmm...

My main algo is:

int numsInColumn = N%2==0?N/K:N/K+1;
StringBuffer s;
for (int i=0; i<numsInColumn; i++)
{
s = new StringBuffer();
for (int j=0; j<K; j++)
{
int id = j*numsInColumn+i;
if (id<=N-1)
s.append(numView[id]);
else
break;
}
out.write(s.toString());
out.newLine();
}
Array numView is supposed to be of a prepared 4-chars long numbers of given sequence.
Where can be the bottleneck? :(

if you make your massiv global you have to write one more if for "0"
