`#4298` lacom

Victor și tatăl său au mers la magazinul de bomboane pentru ca tatăl să își onoreze o mai veche promisiune. Magazinul are bomboanele aranjate pe un rând, în mai multe cutii așezate una lângă alta. Se cunoaște numărul de bomboane din fiecare cutie, în ordinea în care sunt așezate cutiile începând de la intrare.
Tatăl i-a fixat lui Victor următoarea regulă de colectare a bomboanelor:

Parcurge cutiile începând de la intrare.
Colectează toate bomboanele din prima cutie.
Când ajunge la o cutie de pe rând, colectează toate bomboanele de acolo doar dacă numărul lor este strict mai mare decât numărul de bomboane din ultima cutie din care a colectat.

Determinați câte bomboane a colectat Victor.

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 lacom 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.
