/**
din (i,j) pot merge ori intr-un vecin care e si el alb
as mai putea merge in patratul de latura 2n + 1 centrat in (i,j) fara colturile lui
acum, faza funny e ca nu prea ma intereseaza de mersul inauntrul formei ci doar pe marini, unless este celula de finish in interior
asa ca, ori e celula de finish in interior si zic direct gen "boss, dute in aia", ori pun cu cost + 1 celulele de pe margini
acum, ca sa gasesc celulele de pe margini nevizitate inca, trebuie doar sa vad pe niste bucati de linii / coloane care mai sunt alive
asta pot cu un set, dar cu constanta aia :skull: mai bine nu, deci bag aib si cb pe aib

Acum, cum imi fac dfs-ul ca sa nu iasa nimic dubios
In etape, cat timp n-am ajuns la finish, mai intai imi iau celulele cu care n-am trecut prin faza 1 si le dau fill cat au in jur 0
Iar in faza 2 iau celulele care n-au trecut prin faza asta si le fac kinda patratul, iau alea de pe margini etc
