Macarie

#4604

Macarie a primit o nouă temă la informatică, având următorul enunț: Se consideră un șir de numere naturale nenule, A cu N elemente. Fie șirul crescător D format din toți divizorii naturali, nu neapărat distincți, ai elementelor din A. De exemplu, pentru N = 4 și A = (6,2,3,2), avem șirul D = (1,1,1,1,2,2,2,3,3,6). Cunoscându-se un șir Poz format din Q numere naturale nenule, reprezentând poziții din șirul D să se determine, pentru fiecare dintre acestea, elementul corespunzător din șirul D.

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 Macarie 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!
