So I've gotten to the end of my coding for fifteen and sure, I could try and solve it myself (I'm lazy), OR I could load up the 3x3.txt file.

However, I'm having trouble finding the location of this file. When I try to run fifteen with a board size of 3 and then enter the location of the 3x3.txt as specified in the problem set instructions, I get a message saying no file location exists. Is there any way to manually download the file and put it in my Dropbox/pset3/fifteen/ directory?

  • How do you pass the path to the file and what is it? – Kareem Jul 18 '14 at 11:06

First, run update50 to make sure you are up to date. Run appliance50 to verify that you have version 19-2.

Then, run ls ~cs50/pset3

You should see the files there.

As a last resort, download the files directly and place where you want them: http://d2o9nyf4hwsci4.cloudfront.net/2009/fall/psets/3/tests/3x3.txt http://d2o9nyf4hwsci4.cloudfront.net/2009/fall/psets/3/tests/4x4.txt
