#2431 cover

Se consideră N intervale închise, având extremităţile numere naturale cuprinse între 1 şi L. Fiecare număr natural i din intervalul [1, L] are asociată o pondere c[i]. Numim acoperire o mulţime de numere naturale cuprinse între 1 şi L cu proprietatea că fiecare interval conţine cel puţin un element al mulţimii. Costul unei acoperiri este egal cu suma ponderilor numerelor din acoperire.
Pentru un set de intervale dat să se determine costul minim al unei acoperiri.

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 cover 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.
