#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.
