This guy has cheated in almost every contest . He has made three codechef id just to cheat and increase the rating.
All three id’s are of same person. I mean just look at this id ashis_19 | CodeChef User Profile for Code_Kar | CodeChef . How can someone who was performing so bad till july cookoff 2020 suddenly improved a lot just in a matter of few days and got rank of 265 in july lunchtime and rank 469 in august long challenge.
I have checked all the three profiles of this guy .Same cheating case in these contest too by this guy.
3.July challenge.
4.August long challenge.
5. June lunchtime.
6.April challenge.
Codechef kindly look into the matter . I am 100 percent sure this guy cheated in august challenge and july lunchtime . This guy has become 4 star just due to cheating.
All of a sudden people realized oh let’s make patterns of “001101010101” and similar in @EQDIV, People might not have cheated but there was spread of the idea like gossip.
Please get this, community people are doing best to catch those who cheat.
I takes time because it’s free platform and so they have limited servers. And they are doing best to get over it.
May be… but the problem itself was NP and because of the given constraints the solution will give TLE if you use DP. But if you print all the solutions for k=1, it is very easy to see that all of the strings follow some pattern and it was enough evidence to be sure that other subtask can also be solved by pattern.
I have seen people becoming 5* coders because it is impossible to become on their own. Kudos to the code leakers for making fool out of such cheap cheaters.
