Problem descriptionwe define f (a) = 1, f (a) =-1, f (b) = 2, f (b) =-2, ... f (z) = n, f (z) =-26;
Give you a letter x and a number y, you should output the result of y+f (x).
Inputon The first line, contains a number t.then T lines follow, each line was a Case.each case contains a letter and a num ber.
Outputfor the should the result of y+f (x) on a line.
Sample Input
