Problem

The name score is the sum of the scores of every uppercase letter in a name. The score table follows alphabetical order, that is, $A=1, B=2, C=3, \dots, Z=26$ .

For a name $SUNGPIL$ , the score is $S(19)+U(21)+N(14)+G(7)+P(16)+I(9)+L(12)=98$ . For a name $SOYOON$ , the score is $S(19)+O(15)+Y(25)+O(15)+O(15)+N(14)=103$ .

Given a name, write a program that computes its name score.

Input

The first line contains the length $N$ of the name. $N$ is a positive integer not exceeding 100.

The second line contains the name of length $N$ . It consists of uppercase letters only, with no spaces.

Output

Print the name score of the given name on the first line.
