#TC1017 #QUIZ 7<\/p>\n

The last of the quizzes. I wanted to import the lists from text files just to practice doing that, but I had a problem with the unknown sizes of the lists, turns out I only managed to get it working properly if I specify before hand how big each list is. Other wise it was a simple quiz for me since I was also working on my sudoku.<\/p>\n
