How funny. I really can not find what had gone wrong in my code.
I have already test all the data in the discuss founm.

I got AC at POJ, but WA 23 here T_T

3xian is an ACMER from GDUT? Isn't it? haha
OH, I know.
While reading data, dealing with string, must use:
for(i = 0; i < strlen(str); i++)
{
XXXXXXX
}

if use:
i = 0;
while(str[i])
{
i++;
}

will WA 32
It takes me two days to find this fault.

I know what had happened~
When we convert 'char' that ASCII larger than 127 into 'int', we will get negative integer but not the original number.
