#2845

Se consideră o pădure ce conține n•m copaci aranjați pe n linii și m coloane în care s-a produs un incendiu. Pădurarii cunosc coordonatele x și y ale copacului de la care a izbucnit focul și modalitatea prin care acesta se extinde. Astfel, dacă un copac se aprinde într-o anumită zi, în ziua următoare se vor aprind copacii vecini cu acesta pe linie sau coloană care nu sunt încă afectați de incendiu.

Știind x și y, coordonatele inițiale ale focului și n și m, dimensiunile pădurii, ajutați pădurarii să determine numărul de zile după care va fi afectat fiecare copac al pădurii.
