Norocos

#1694

Un număr natural nenul m se numește norocos dacă pătratul lui se poate scrie ca sumă de m numere naturale consecutive. Un număr natural m se numește k-norocos, dacă este egal cu produsul a exact k numere prime distincte. Observați că între cele două proprietăți definite nu există nicio legătură.

Dându-se k și N numere naturale, scrieți un program care să determine:

a) Cel mai mic și cel mai mare număr norocos dintre cele N numere citite
b) Câte numere k-norocoase sunt în șirul de N numere citite

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 Norocos 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!
