Gradina Piticului

#1481

Un pitic pasionat de numere trebuie să-și pună flori în grădină. El are de plantat m rânduri cu flori, aceeași floare pe tot rândul. Rândurile sunt numerotate de la 1 la m. Având la dispoziție suficiente specii de flori, piticul nostru s-a gândit să le planteze folosind următorul algoritm matematic: pe rândurile care sunt numere prime, va planta exact floarea numerotată cu numărul prim respectiv, iar pe celelalte rânduri va planta floarea numerotată cu suma divizorilor primi ai numărului neprim.

Să se realizeze un program care să afişeze ordinea de așezare a florilor pe cele m rânduri.

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 Gradina Piticului 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!
