SmallTalk Collection

Hi guys,

I am just beginner in Smaltalk and I have some problem with collection in smalltalk.
For this problem I have to define the value of an alphabetic character based on its location in the alphabet. So ‘a’ and  ‘A’ each have value 1, ‘b’ and ‘B’ each have 2, etc. Non-alphabetic characters can be considered to have value 0.
The value of a word is the sum of the value of all its characters. So ‘Smalltalk’ has value 101 and ‘abc’ has value 6.
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').

Please kindly help me guys. Really appreciate your help.

Thanks.
     

This is obviously a class problem and the members here
are not inclined to provide answers to class problem.
However, you can get help here. But, you need to break
down the problem yourself and ask specific questions.

Hi,

Terry is right that is more a "class" problem, but for fun:

str := 'Smalltalk'.
sum := str sum: [:c |   (c isAlphabetic  ifTrue: [c asLowercase
asInteger - 96 ] ifFalse: [0])].
^sum

You can run the code in a  Workspace.

Success ..

As far as I've understood the taks I've written a simple recursive solution. Source is attached.
Is this what you're looking for?

This is one of my students asking about a class assignment. The  
statement of the problem below is incorrect. I direct the student to  
the class wiki (http://www.eli.sdsu.edu/cgi-bin/wiki/page.ssp?wikiname=CS535&pagename=Questions+about+Assignment+3 
) where there is more information about that problem. I do have office  
hours before class today (4:15-5:15 pm) and later in the evening  
(8:30-9:30 pm). The student should make use of one of those times to  
talk to me so that they understand the problem correctly. I will talk  
to my class today about inappropriateness of using this mailing list  
to ask for solutions to homework problems.

So I shouldn't respond with my solution that implements goto for  
smalltalk and solves it using gotos entirely?

You should not  respond the solution  with "GO TO" prior to publishing
solution with complete implementation of "CASE" and  "CAST" alternatives...

I hope that means that students who perused this list will get bonus
points.
Social skills and a network embedded in the Smalltalk community are
considered pros when we select new people.

Of course we should consider it a big minus if students fail to mention
that the subject at hand is a homework assignment...
