OJ Board

I can't understand, the problem say:
The input begins with an integer n on a line by itself representing the number of blocks in the block world. You may assume that 0 < n < 25.

So I can define table[25][25], but even when I use table[200][200], it's still out of range.

Who can help me?
I got this when compiling:
Your program has died with signal 11 (SIGSEGV). Meaning:

Invalid memory reference

Before crash, it ran during 0.010 seconds.

and this is my source in C:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>

int table[200][200];
int a,b, posa ...
