#1949 tort_LMA

Un celebru rezolvitor de pe pbinfo împlinește venerabila vârstă de n ani. Ceilalți rezolvitori s-au gândit să îi facă o surpriză și să comande un tort special. Acesta are mai multe nivele, toate având forma pătrată, astfel:

  • primul nivel este format din n*n prăjituri fiecare având prețul de 1 leu și având scris numărul 1 în partea de sus.
  • al doilea nivel se suprapune peste primul exact la mijloc și este format din (n-2)*(n-2) prăjituri fiecare având prețul de 2 lei și având scris numărul 2 în partea de sus.
  • al treilea nivel se suprapune peste al doilea exact la mijloc și este format din (n-4)*(n-4) prăjituri fiecare având prețul de 3 lei și având numărul 3 în partea de sus.
  • ș.a.m.d.

a) Calculați și afișați numărul de nivele pe care le are tortul special.
b) Afișați tortul, așa cum se vede dacă este privit de sus.
c) Calculați și afișați prețul tortului.

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 tort_LMA 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.
