#2610 Discuri

Se dau N numere reale considerate ca fiind razele a N discuri. Considerăm că așezăm un disc în sistemul xOy dacă îl plasăm la o coordonată x pozitivă suficient de mare, tangent cu axa Ox și deasupra ei, apoi îl împingem spre Oy până când devine tangent cu Oy sau cu primul disc așezat anterior întâlnit. În figura rezultată după așezarea tuturor discurilor în ordinea dată unele dintre ele pot fi considerate dispensabile, pentru că prin eliminarea lor nu se modifică lățimea totală a figurii, adică nici un disc nu se mai poate deplasa spre stânga. Identificați toate discurile dispensabile din figură.

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 Discuri 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.
