Manole este extrem de răcit. Din această cauză a mers la medicul de familie care l-a sfătuit urmeze un tratament cu N pastile, din care trebuie să ia în fiecare zi câte o jumătate. A cumpărat de la farmacie o cutie în care se aflau exact N pastile, fiecare dintre ele având pe suprafață o dungă care marchează jumătatea ei.
Manole începe să își ia tratamentul și constată că poate proceda doar astfel:
- scoate din cutie o pastilă întreagă din care folosește, în ziua respectivă, doar jumătate din ea, iar jumătatea rămasă o pune înapoi în cutie;
- scoate din cutie o jumătate de pastilă, rămasă din una din zilele anterioare, pe care o folosește în ziua respectivă.
Scrieți un program care determină numărul de posibilități în care poate lua toate cele N pastile, procedând după procedeul descris mai sus.

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 Pastile 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.
