Recently, when I was wandering around Codeforces Round 970 (Div. 3) submissions, i have noticed some aditya8806701281's submissions seem to be suspicious. This user has never ranked higher than 5000 in any contest before but in this contest he rose to the top 500. Have a look:

Problem 2008H - Тест Сакурако: 279214387 As you can see, too many long-name variables and there is an unnecessary function (right after the defines) that he calls for nothing in the solve function.

Problem 2008G - Задание Сакурако: 279207870 The same thing from his solution from problem H.

Problem 2008F - Коробка Сакурако: 279133796 Variable names seem too long.

Problem 2008D - Хобби Сакурако: 279107529 2 extra functions for nothing, and he called them in the solve() function.

Problem 2008C - Самый длинный хороший массив: 279099481 Do you think the function randomOrder1() has any purpose?

Problem 2008B - Квадрат или нет: 279087122 I don't think he even cheated on B div3, but have a look. 2 randomFunction with no purpose.

Problem 2008A - Экзамен Сакурако: 279078136 If he cheated on A div3, idk what is he doing here. But I saw the "randomFunction" and yeah, who even do that?

Sorry for my poor english, but above are the things I wanted to say and might be worth considering.
