#2999 submultimi_2

Pentru un număr natural n se generează submulțimile de numere naturale de forma {0} {1, 2} {3, 4, 5} {6, 7, 8, 9} ... unde ultima submulțime are n elemente.

Scrieți un program care citește de la tastatură trei numere naturale n, k și r și afișează:

  • câte submulțimi sunt formate dintr-un număr de elemente pare(cardinalul submulțimilor este un număr par)
  • media aritmetică a elementelor din submulțimile cu număr de ordine k și r (0 < k ≤ r ≤ 100)
  • elementele submulțimii r sub forma: primul, al doilea, ultimul, al treilea, al patrulea, penultimul, etc.

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 submultimi_2 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.
