I don't remember, but someone mentioned that there were lots of similar submissions to E1, when I looked at the suspicious submissions, they had one thing in common: memory consumed was equal to 8089600 bytes, so I ran some python and obtained these submissions(lets see how many are detected by plag-checker):

277426958, 277425890, 277425852, 277424914, 277424565, 277418774, 277418655, 277418511, 277418081, 277417714, 277417556, 277417035, 277416988, 277415986, 277415655, 277415207, 277414924, 277414655, 277413989, 277413413, 277413097, 277412884, 277412728, 277412417 rest I am commenting due to word limit

So I have some categories, I want you to vote the best cf user for(you can vote more than one user in a category, and vice versa):

1)Unique/Creative solutions

2)Coding with best practices(no repetition, grouping similar code etc..)

3)Most readable code(naming conventions..etc)

4)Use of unique data structures

5)Best cheating practices(unique ways to hide cheating, code obfuscation, etc)

+you can add your own category!
