Lab 8 - Fall 2019

Word Puzzle

The purpose of this laboratory exercise is to practice working with lists and recursion, and to develop a complex algorithm.

At the command line:

1. Create a new directory for this lab in your cs101 directory by entering the following at the Linux prompt:
   1. cd
   2. cd cs101
   3. mkdir lab8
   4. cd lab8
2. Launch DrRacket.
3. Select Racket / Limit Memory. Make sure Limited is selected and type in 512 MB. Restart Dr Racket to see the updated limit.
4. About dictionaries... Conveniently for those of us using Linux or OSX, the dictionary for both operating systems is found at /usr/share/dict/words. If you are using another OS, download the list of words here. All of us can refer to the explanatory text near figure 74 in the text for more information. The figure itself is:

; On OS X: 

(define LOCATION "/usr/share/dict/words")

; On LINUX: /usr/share/dict/words or /var/lib/dict/words

; On WINDOWS: borrow the word file from your Linux friend

; A Dictionary is a List-of-strings.

(define AS-LIST (read-lines LOCATION))

1. Start reading at 12.3 in our text. Work as many of the exercises from 209 to 214 as you can. Submit what you finish on Moodle by the end of class. (I'll share my completed code with you tomorrow so you can use it as a starting point for our next assignment.)
