Se consideră o clădire de formă dreptunghiulară formată din n*m camere, dispuse pe n linii și m coloane. În fiecare cameră se află o cantitate cunoscută de bomboane. Intrarea în clădire este în camera de coordonate (1,1), iar ieșirea în camera de coordonate (n,m). Din orice cameră (i,j) se poate ajunge numai în camerele (i+1,j) sau (i,j+1), fără a părăsi clădirea.
Un copil intră în clădire, parcurge un șir de camere după regula precizată și iese din clădire, luând din fiecare cameră în care intră toate bomboanele existente. Determinați cantitatea maximă de bomboane care poate fi culeasă precum și un traseu prin clădire în care se adună cantitatea maximă de bomboane.

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 Cladire2 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.
