#882 Lac

Se dă harta unui lac de formă dreptunghiulară, împărțit în n*m zone dispuse sub forma unei matrice cu n linii și m coloane. Zonele pot fi acoperite cu apă, sau pot fi zone de uscat. Zonele de uscat care sunt învecinate pe linie sau pe coloană formează insule sau peninsule. Peninsule conțin cel puțin o zonă de uscat pe marginea lacului (matricei), în timp ce insulele sunt situate în întregime în interiorul lacului.

Cunoscând harta lacului, determinați numărul de insule și numărul de peninsule.

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 Lac 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.
