#4591 fantastic

În Ajunul Crăciunului, așteptându-l nerăbdători pe Moș Crăciun, Andrei și Bogdan se hotărăsc să joace un joc, căștigătorul jocului fiind primul care va primi cadoul de la acesta. Ei scriu pe n bilete n numere naturale, câte un număr pe fiecare bilet. Fiecare extrage câte un bilet dintr-un bol. Un bilet este norocos dacă numărul scris pe el este număr fantastic. Un număr este fantastic dacă are număr par de cifre și este multiplu de 2024. Câștigătorul jocului este cel care extrage cele mai multe bilete norocoase. Dacă la finalul jocului cei doi băieți au extras număr egal de bilete norocoase sunt amândoi considerați câștigători și vor primi cadoul în același moment de timp. Cunoscând numărul n de bilete precum și numerele scrise pe cele n bilete, determinați care este numărul total de bilete norocoase extrase de cei doi copii.

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 fantastic 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.
