#1544 Muzical C++

Gigel în timp ce așteptă să meargă la doctor se joacă cu noul lui telefon. A observat ca atunci când este pe ecranul de start și apasă pe o tastă numerică se aude o notă muzicală.

Dar lui i-a venit ideea să codeze fiecare notă muzicală în acest mod:

  • Nota do1 cu numărul 0
  • Nota re cu numărul 1
  • Nota mi cu numărul 2
  • Nota fa cu numărul 3
  • Nota sol cu numărul 4
  • Nota la cu numărul 5
  • Nota si cu numărul 6
  • Nota do2 cu numărul 7

El creează un cântec, ia notele muzicale și le codează ca mai sus, le adună, iar apoi împarte suma la 8 și restul rămas este nota maximă.

Ajutați-l pe Gigel sa afle nota maximă!

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 Muzical 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.
