Can someone provide more tests?
I am using scanner.nextLine() to read
line.charAt(pos) == '?' to compare in java and also Josephus allgorithm:
jos[1] = 1;
for (int i = 2; i < max_n; i++) {
    jos[i] = (jos[i - 1] + 1998) % i + 1;
}
My code is so small that I don't even know where is the bug

Ok, the thing is I misunderstood the problem.

You read ALL the input ignoring new lines, and then do the 'process'.
I was reading line by line and doing 'process' for each line.
Hope it will help the others.
