td;dr I’m back and expect lots of algorithm + elixir posts here 
So I was burned out and depressed since December. Which is why last year’s AoC thread saw me suddenly vanish, I was less chatty and i had almost 0 personal project contribution this year, until today 
Been feeling better since mid-feb and am fully motivated and energetic since last week. I started with a lighter data structure like Min/Max Stack and algorithm like Catalan number.
Planning on dealing with Disjoint Set, Lavenstein and starting off with Graph from next week. Stay tuned.
