`#1576` zona3

Se consideră o matrice cu n linii și m coloane. Spunem că o poziție este liberă dacă elementul de pe linia i și coloana j este egal cu 0 și 1 în caz contrar. Spunem despre mai multe elemente ocupate că formează o zonă, daca elementele se învecinează pe cele patru direcții (sus, jos, dreapta, stânga).

Calculați pentru fiecare zonă numărul de elemente și afișați noua matricea formată prin înlocuirea elementelor egale cu 1 cu numărul de elemente pe care îl are zona din care face parte elementul respectiv.

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 zona3 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.
