D1 was easy though couldn't solve D2

[@RastyRocky]

Can you please make a video on selecting problems for practicing and which resources do you use learn for learning topics?

[@cfstepofficial]

Someday in future, sure, once the channel has wider reach. For now, you can transfer this request to Aryan's channel.

[@RastyRocky]

@@cfstepofficial Sure, if not a video can you please suggest something in the comment section itself?

[@cfstepofficial]

@@RastyRocky You can ask on my (or aryanc403's) discord server.

[@Xtronix90]

wondering which is your real cf handle? thank you the explanation.

[@cfstepofficial]

adaptatron is my real handle. If I had a high rated alt, wouldn't I have promoted by youtube content through that account for faster growth :)

[@Xtronix90]

@@cfstepofficial then why don't you increase your rating, its not the case that you cannot ;) , you solved D1 in an hour or so

[@cfstepofficial]

@@Xtronix90 I can, but sometimes even if I don't attempt entire contest, I like to take a look at problem C or D, and submit it during the contest if I am able to solve it. Doing so will naturally decrease my rating again, so that's why I don't bother increasing it.

@@cfstepofficial your views differ from most of the crowd, in a good way. are you already employed??(question out of curiosity)
