I slipped and left a copy of an answer to some of the exercises to workbook 4 in the code. There is a comment that says “don’t give to students.”
Since it’s out, you have access to it.
I recommend that you try to do the problem without peeking at my answer. But, since you have my answer, I can’t stop you from checking your answer (or even copying it outright).
To make it easier to avoid peeking, we updated the repository so that the example solution is removed. So, if you have not yet created your repo, it won’t be in the current version. However, we did not go back into the commit history to delete the code: you can go back to an old commit to see the answer.
Note: no promises that the answer I accidentally left in the code is correct. I did not intentionally try to trick people, but I also didn’t check the version that is there.
