Problem Description

we define f(A) = 1, f(a) = -1, f(B) = 2, f(b) = -2, ... f(Z) = 26, f(z) = -26;
Give you a letter x and a number y , you should output the result of y+f(x).

 

Input

On the first line, contains a number T.then T lines follow, each line is a case.each case contains a letter and a number.

 

Output

for each case, you should the result of y+f(x) on a line.

        int t=input.nextInt();
        while (t-->0){
            char ch=(input.next()).charAt(0);
            int in=input.nextInt();
            int ch_i=0;
            if (ch>='A'&&ch<='Z'){
                ch_i=ch-64;
            }else if (ch>='a'&&ch<='z') {
                ch_i=-(ch-96);
            }
            int sum=ch_i+in;
            System.out.println(sum);
        }
    }
