#2785 galeti

Avem n găleți numerotate de la stânga la dreapta numere de la 1 la n. Fiecare găleată conține inițial 1 litru de apă. Capacitatea fiecărei găleți se consideră nelimitată. Vărsăm gălețile una în alta, respectând o anumită regulă, până când toată apa ajunge în prima găleată din stânga. Vărsarea unei găleți presupune un anumit efort. Cunoscând numărul de găleți n și un număr natural e, să se determine o succesiune de vărsări în urma căreia toată apa ajunge în găleata cea mai din stânga și efortul total depus este exact e.

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 galeti 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.
