Hi everyone, Quarantine, though necessary, is honestly a tad boring, especially the months between school and college. So........ I recently started a Youtube channel (coz why not), and intend to post some solutions to OI Problems I have solved in the past year. I will discuss solutions from POI/BOI/CEOI/JOI etc, and expect the problems to be from 1900-2600 difficulty level (?!). Obviously, these will be just the problems I have managed to solve, with/without help, so they won't be super tough. Also, some of these problems might not have proper editorials or at least English translated ones, so hopefully, it will be useful.

The problem statement and AC codes are linked in the description.
These are pretty easy, maybe around 2000 level (?!). I'll maybe do a few easier problems and once I gain a bit more experience, I'll post solutions of the harder ones.
Feedback is appreciated.
