Have you searched the Volume V for a thread about this problem? There should be one about it and the content can answer your question.

Please searched the forum before posting question.

Yes, you are right~

Oh, they are~

To me, a line is a "contracted" rectangle, and a point is a "contracted" line~

This implies that you have not considered some special cases of the problem

No, the judge will also feed the inputs from the files~

Quoted from the words of the problem setter:

When I did mathematics a lot factorial of negative numbers was a very interesting issue to me. If factorial(-1) is not infinity then why is
C(4,5) = 4!/((5!)(-1!)) = 0, have you ever thought it this way. I am getting many complains on this issue, some ...

Before checking the outputs, I wanna ask: "Did you got wrong answer or something other than Accepted?"

I have not taken a in-depth look at your algo, but the first thing come to my attention is the use of recursion. RE will be caused is there's stack overflow, i.e. when the number of times recursion is called is too much.

For the input problem you mentioned, you can write the input data in a file ...

Causing buffer overflow is the size of the string, but not choosing gets or fgets. Therefore to prevent buffer overflow, it's better to allocate an enough size of string size.

You can use gets.

If it's a blank line, the string get from gets is of strlen 0.
e.g. for a program runs until reading a blank line:
[c]char line[100000];
while(gets(line))
{
if(strlen(line) == 0) break;
......
}
[/c]

If it's the EOF, the gets returns NULL.
e.g. for a program runs until the EOF ...

My IE, being the same version, does not have such problem.

Is this your PC problem? =P

No need~

Actually you have no need to store up all the input data before outputing your answers. Just loop number_of_case times for your input and output procedure~

Oh... you can re-add the BEGIN_OR_SOURCE_CODE and END_OF_SOURCE_CODE by bracketing with /* and */ to fix the *advertisement* problem with your email client.

I think you better have a look at a thread in the Real Time Clarification, which is about this problem.

This problem is not as easy and straightforward as you think~

I copied and pasted your codes and submitted. It did not return compile error.....

What means do you submit your program by?

There are initially 17 people namely
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
(^ means current position) with m = 5,
firstly 1 is eliminated, so it becomes:
^2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17
counting 2 3 4 5 and eliminate 6, so it becomes
2 3 4 5 ^7 8 9 10 11 12 13 14 15 16 17
counting 7 8 9 ...
