Olympiads school comp contest lvl ~~1~~ ~~2~~ 3 4 kid

Can't do graph theory or dynamic programming to save my life 😔

ki ki ki, kimi no koto, WA WA WA TLE TLE TLE 😤

imagine fast submissions this meme was made by slow ass java user 😒 (Not to be anymore since i'm switching to C++ 😎)

Started the transition to C++ from Java. (August 5, 2020)

My main language is now C++. The transition has been completed. (August 16, 2020 - 11 days)

do homework... or do dmoj? 🤔

Gotta get better at contests no more 🐒 mode allowed
