#2706 serbare2

Majoritatea copiilor sunt sociabili și relaționează ușor cu cei de vârsta lor dar sunt și copii mai timizi sau mai puțin atrași de activitățile de grup. În urma studierii comportamentului unui eșantion de n copii, s-a stabilit, pentru fiecare doi copii dacă relaționează sau nu. Pentru serbarea de sfârșit de an, s-a propus realizarea unei scenete și este necesară selectarea unei grupe cât mai numeroase de micuți dar fără a depăși k, numărul maxim de personaje. Rolurile presupun interacțiunea fiecărui copil selectat cu toți ceilalți mici actori care joacă în scenetă. Să se determine cel mai mare număr de copii care pot fi implicați în serbare, știind ca fiecare dintre aceștia trebuie să relaționeze cu toți ceilalți copii din scenetă.

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 serbare2 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.
