The value of the letters

Your task is to write a program that computes the value of a given
message. To compute it, we will consider that only the letters have
value, and that each letter has greater value the more infrequent it is,
as can be seen in this table:

   Valor  Letras
  ------- ---------------------
     1    a e
     2    o s
     3    d i n r
     4    c l t u
     5    m p
     6    b f g h j q v x y z
     7    k w

Input

The input consists of a sequence of characters, which include
exclusively lowercase letters, spaces and newlines.

Output

Your program must print the total value of the message, computed as the
sum of the value of all its letters.
