Congratulates! \O/\O/\O/ Congratulates!

Hoping he will reach CM the 5-th time soon!

For Example:

cftwooo.two, Barthmalemew, DarkMiss

Seems they all used AI.

About cheaters last Edu-Round, see this post.

At least $$$4$$$ cheaters in top $$$5$$$, $$$5$$$ cheaters in top $$$12$$$, amazing!

jack_l_b_b

Reason:

Different Coding Styles in problem B, C, F. (different variable naming method, one of them use std::vector while his other problems' solution used C-style arrays)

chenzheyuan, hprwhgsafwan12 and not.found

Similar code on problem C, D.

Also seems hprwhgsafwan12 used AI too.

Strange variable naming method.

Different header use styles.

thank you SYCu

UPD 1.1

his explanation (copied from his private message to me):

Good, Sir
 I didn't cheat, i was eating and explaining the compilation to my little brother who is starting to code. I use the same style, i dont like long coventions which ais do, all of my codes are hardcoded, i can explain the maths to you if you want me to over here? the latest problem i solved using graph routing on a 2d grid 

UPD 2

Some user reported AnupamRoy12 is a cheater. Since I'm not very sure, but I still put him here. I'd say there's a $$$70\%$$$ chance he's a cheater.

Strange code comments.
