FAQs

1. Q: For rme.hs I know that using strings (lists of characters) are prohibited, but would it be ok to use a list of integers?
   A: I'd want to see your solution to be sure, but anything that employs a list is most likely not using an arithmetic approach.

Corrections

1. The second paragraph of the write-up for squares.hs in the handouts says that a square's upper-left corner is represented by a row and column number but in fact the upper-left corner represents an (x,y) coordinate!

   Here's a corrected and improved version of that second paragraph:

   A square is represented with a four-tuple that specifies the square's upper-left corner (x and y coordinates), its size (i.e., width and height), and a two-character string that specifies the square's border and fill characters. For example, (8,4,5,"*+") specifies a square with its upper-left corner at (8,4); a width and height of 5; and '*' and '+' for its border and fill characters, respectively.

2. The handouts show observations.txt as "Problem 10" but it should be "Problem 8".
