I've created a workspace in the shared Dropbox folder, and I created a Scala project for each of you within it. I copied my code into my Scala project, but I didn't copy any other code.  Let's see if we can use that workspace as a shared work area.  Please try this workspace in the Scala eclipse environment and let me know if it works for you. Does my code appear in the workspace when you switch to it? Does it run?  (For whatever reason the Georgia and Bob worksheet wasn't downloaded correctly yesterday. It's correct now. Does it work for you?) Post a note here when you have some working code in one of your projects. I'll see if I can run it. To run someone else's code may require that you open the project and then do a Refresh: select the project, right click and select Refresh, or select the project and press F5.

For Jeffrey's sake (and everyone else) I'll repeat that we decided to stay with the same problems as last week for a second week. I have solutions for all but the Knight's Journey. You are welcome to look at my code and base yours on it, but please be sure you can explain any part of my code that you use.

Daniel,

I still don't understand how your Alphacode gets the right answer. (I can't find your code to look at it.)  You seem to look ahead but count behind. Why should that give the right count? Whether there are one or two interpretations of the current character shouldn't have anything to do with what led up to that character. In addition, the one or two interpretations effect how the subsequent characters are interpreted, not how the previous ones are.  Can you explain why it works.
