Rezumat problemă

Clasa
#2802

Se citește de la tastatură numărul n și un număr p cu valoarea 1 sau 2 și apoi n șiruri de tip nume prenume media1 media2 media3 separate prin spații.

Pentru p=1, se va afișa numărul elevilor care au media generală mai mare sau egală decât media clasei.

Pentru p=2, se va afișa pe primul rând media clasei și pe următoarele n rânduri, numele, prenumele și media generală a fiecărui elev, separate printr-un singur spațiu, sortat descrescător după medie; la medii egale se sortează crescător după nume, iar la nume egale crescător după prenume.

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 Clasa 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!
