#3624 bal1

Tocmai a ajuns la balul din sat un grup de n fete numerotate de la 1 la n. Acolo sunt așteptate de m băieți frumoși, numerotați de la 1 la m. Fiecare băiat i (i=1..m) are un coeficient de frumusețe b[i]. Fetele nu acceptă orice băiat la dans. Fata i va accepta să danseze cu un băiat doar dacă băiatul are un coeficient de frumusețe mai mare sau egal cu f[i]. Cunoscând coeficienții de frumusețe ai băieților, b[1], b[2], …, b[m] precum și coeficienții preferințelor fetelor, f[1], f[2], …, f[n], să se determine numărul maxim de perechi de dansatori care se poate forma.

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 bal1 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.
