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 6 R 1 P 2 G 3 r 1 p 2 g 3 Sample Output 19 18 10 -17 -14 -4
