Concurs2
#1753

La un concurs de programare s-au înscris n elevi. Concursul se desfăşoară pe două secţiuni, secţiunea 1 pentru începători şi secţiunea 2 avansaţi. Proba de concurs se desfăşoară pe parcursul a 3 ore şi elevii au de rezolvat 2 probleme.
Fiecare problemă poate avea punctajul minim de 0 puncte şi punctajul maxim de 100 de puncte. Punctajul final al concurentului este format din suma punctajelor celor două probleme. Să se scrie un program care citeşte numărul de elevi înscrişi şi apoi date despre fiecare elev înscris (secţiunea la care s-a înscris, punctajul obţinut pentru prima problema şi punctajul obţinut pentru a două problemă) și rezolvă următoarele cerinţe:

1. Afișează mesajul DA dacă toţi cei N elevi înscrişi au reuşit să obţină un punctaj nenul la ambele probleme propuse, respectiv NU” în caz contrar.
2. Afişează pentru fiecare secţiune numărul de elevi înscrişi. Afişarea se va face în ordinea crescătoare a numărului secţiunii, prin perechi de numere de forma nr_secţiune nr_elevi.
3. Afişaţi pentru fiecare secţiune punctajul maxim obţinut şi numărul de elevi care au obţinut acest punctaj. Afişarea se va face în ordinea crescătoare a numărului secţiunii, prin triplete de numere de forma nr_secţiune punctaj_maxim nr_elevi. Ştiind ca premiile se acordă doar celor care au luat punctaj maxim, afişaţi şi numărul de premii care vor fi acordate.

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 Concurs2 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!
