`#1595` Bomboane1

Lui Cristian, ca oricărui alt copil, îi plac bomboanele. A primit cadou de la prietenii lui cutii cu bomboane. Fiind multe cutii le-a numerotat: 1, 2, 3, … Desfăcând câteva, a văzut că există o legătură între numărul de pe etichetă și numărul de bomboane din cutie. Astfel în fiecare cutie sunt atâtea bomboane câți divizori pari are numărul de pe cutie. De exemplu cutia cu numărul 10 conține 2 bomboane, cutia cu numărul 8 conține 3 bomboane ș.a.m.d.

Cristian a ales la întâmplare două etichete x și y dorind să desfacă toate cutiile cu etichete cuprinse între x și y. Ajutați-l să determine prima cutie, etichetată cu a, și utima cutie, etichetată cu b, cu număr maxim de bomboane (x≤a≤b≤y), câte cutii n sunt cu acest număr de bomboane și care este acest număr d de bomboane.

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 Bomboane1 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.
