题意：字母替换成数字，求和，简单~~

代码：

# include <stdio.h>
# include <math.h>


int main ()
{
    int T, num ;
    char ch ;
    scanf ("%d%*c", &T) ;
    while (T--)
    {
        scanf ("%c %d%*c", &ch, &num) ;
        if (ch >= 'a' && ch <= 'z')
            num -= (ch-'a'+1) ;
        else
            num += (ch-'A'+1) ;
        printf ("%d\n", num) ;
    }
    return 0 ;
}
