string-sum
Source: hackerearth
Difficulty: EASY

Consider All lowercase Alphabets of the English language. Here we consider each alphabet from a to z to have a certain weight. The weight of the alphabet a is considered to be 1, b to be 2, c to be 3 and so on until z has a weight of 26. In short, the weight of the alphabet a is 1, and the weight of all other alphabets is the weight of its previous alphabet + 1. 

Now, you have been given a String S consisting of lowercase English characters. You need to find the summation of weight of each character in this String.  

For example, Consider the String aba
Here, the first character a has a weight of 1, the second character b has 2 and the third character a again has a weight of 1. So the summation here is equal to :
 1  + 2 + 1 =  4    

Input Format:
The first and only line of input contains the String S. 

Output Format 
Print the required answer on a single line

Constraints
 1 ≤ |S| ≤ 1000    

SAMPLE INPUT
aba

SAMPLE OUTPUT
4

Explanation for the Sample has been given in the Problem Statement.
