`#398` Plopi2

De-a lungul principalei străzi din orașul nostru există n plopi, pentru fiecare cunoscându-se înălțimea. Primarul orașului dorește ca plopii să aibă înălțimile în ordine descrescătoare. Pentru aceasta, este posibilă tăierea dintr-un plop a unei bucăți – este o tehnică ecologică, nevătămătoare, în urma căreia plopul nu are de suferit. Plopii nu pot fi înălțați în nici un fel.

Determinați numărul minim de plopi din care se va tăia și lungimea totală minimă a bucăților tăiate.

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 Plopi2 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.
