Iceberg

#1451

Se dă o matrice reprezentând o zonă dintr-un ocean ce conține un iceberg; valorile egale cu 1 fac parte din iceberg, iar cele egale cu 0 reprezintă apă.

Se știe că icebergul este înconjurat de apa (nu există nici o valoare de 1 pe marginea matricei) și că într-un interval de timp se topesc toate zonele icebergului care au cel puțin doua laturi vecine cu apa.

Determinați și afișați cate intervale de timp sunt necesare ca icebergul să se topească în întregime. De asemenea, afișați pentru fiecare interval de timp câte poziții de gheață are icebergul la începutul intervalului.
