Hello everyone!
As the Kanpur Regionals have already concluded I tried upsolving the problems in the mirror contest. I managed to do half of the problems but am unable to approach the problems Sumful Triplets, Pocket-less Billiards, Lit 'em Up!, Sequence. As there is no official editorial available yet and there is no access to the official submissions so if someone who has solved these problems might share their solution ideas that would be great.
