An easy problem

#include <stdio.h>
#include <stdlib.h>
int main()
{
    int n,i,j,t,m,x;
    char ch;
    while(scanf("%d",&t)!=EOF)
    {
        while(t--)
        {
            getchar();
            scanf("%c%d",&ch,&n);
            if(ch>='a'&&ch<='z') x=-(ch-'a'+1)+n;
            if(ch>='A'&&ch<='Z') x=ch-'A'+1+n;
            printf("%d\n",x);
        }
    }
    return 0;
