> The puzzle itself wasn't very difficult, you could do it by hand if you really wanted to, but it required you to know how to read and parse lines in a file, handle compound data structures, iterate through, and perform basic operations (floor, casting strings to ints, etc). I don't believe that it required any compound data structures, just looping through the lines in the file. You're right about the rest, though.
