`#2781` Wildfire

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 minim de zile după care întreaga pădure va fi afectată.

Cum funcționează evaluarea?

www.pbinfo.ro permite evaluarea a două tipuri de probleme:

probleme la care rezolvarea presupune scrierea unui program complet
probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.

Problema Wildfire face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:

Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.

Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.
