#1492

Mă gândeam la execuția unui program care calculează formula fericirii. Am o problemă cu alocarea memoriei. În unele cazuri programul poate rula, iar în altele nu. Programul funcționează corect dacă se alocă memorie în primul spațiu liber din zona de date, în ordinea în care variabilele sunt declarate. De asemenea, adresa de memorie a unei variabile succede adresa de memorie a oricărei variabile declarate înaintea ei.

Cunoscând dimensiunea memoriei M, numărul de zone ocupate N, numărul R de variabile declarate, cele N intervalele de memorie ocupate, precum și spațiul ocupat de fiecare din cele R variabile, să se determine:

a) Dimensiunea totală disponibilă pentru variabilele folosite.
b) Adresele de memorie pentru fiecare variabilă în parte în cazul în care alocarea memoriei este posibilă, respectând cerința problemei, sau numărul de variabile ce au putut fi alocate și adresa maximă la care este salvată o variabilă de memorie.

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 Bunicul 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!
