An easy problem

Problem descriptionwe 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 shoshould output the result of Y + f (x ). inputon the first line, contains a number t. then T lines follow, each line is a case. each case contains a letter and a number. outputfor each case, You shoshould the result of Y + f (x) on a line. sample input6r 1 P 2G 3R 1 P 2G 3 sample output19 1810-17-14-4
