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.

 

 

Sample Input
