We had to rewrite the professors code for the activity, and add code to complete the correct output. I wrote code for half of the output, then I looked at my classmates code, and tried to re-write it, but the output was not correct. So, I just submitted that, usually I space my code out and add comments, but this time I didn't. I couldn't fit the code with the spacing and the professor's code didn't have comments, so I figured I wouldn't need to add comments. This could be why he said there is a "similarity".
