[Newbies] Collection in Smalltalk

[Marcin Tustin]

You need to break this down into its component parts:
Write a method that tells you score of a character
Write a method that tells you the score of a string (hint: use inject:into:)
Write a method that tells you the dollar words (hint: use select: and
splitOn:)

> 'b' and 'B' each have 2, etc. Non-alphabetic characters can be considered to

> The value of a word is the sum of the value of all its characters. So

> A dollar word is a word whose value is 100.  I want to add a method to the
> String class that returns all the dollar words in the string.

> So for example if the input is 'SmallTalk' the result is ('SmallTlk'
> 'SmllTlk').
