Arme
#1063

Vasile joacă (din nou!) jocul său preferat cu împuşcături. Personajul său are la brâu N arme, aşezate în N huse speciale, numerotate de la 1 la N. Arma din husa i are puterea pbi (1≤i≤N).

În camera armelor a găsit M arme, aşezate pe perete, în M locaţii, numerotate de la 1 la M. Pentru fiecare armă j (1≤j≤M) este cunoscută puterea sa pcj.

Vasile poate înlocui arme pe care le are la brâu cu arme aflate pe perete în camera armelor. La o înlocuire el ia arma de pe perete din locaţia j (1≤j≤M) şi o pune la brâu în husa i (1≤i≤N), iar arma din husa i o pune pe perete în locaţia j.

Scrieţi un program care să determine suma maximă a puterilor armelor pe care le va avea la brâu Vasile după efectuarea înlocuirilor.

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 Arme 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.

Du-te sus!
