Advent of Code 2025 had only 12 puzzles, but the last one taught me something new. The "sample" data was solved quickly with BFS, but the real event input would have taken millions of years. (1/3)

Eräästä OneDrivestä näyttää puuttuvan yksi #Mikrobitti. Mikähän numero se on ollut?

FYI "Olympiakomitea on pyytänyt kaikkia jäsenjärjestöjään tiedottamaan jäsenilleen, että urheilun oikeusturvalautakunnan sähköposti on kaapattu. Urheilun oikeusturvalautakunnan nimissä on lähetetty kalasteluviestejä, joissa linkki johonkin asiakirjaan. Älkää missään nimessä avatko sitä!"

Today's Part-2 is NP hard and you can basically just optimize the data struct.
