#4655

Andra are un pachet cu n tipuri de buline de ciocolată, cu câte c[i] buline de fiecare tip i. Andra dorește să utilizeze toate bulinele pentru a construi piramide, fiecare fiind formată din unul sau mai multe rânduri, numerotate începând de la 1. Pentru fiecare piramidă în parte, pe rândul i, se află 2i-1 buline. Spre exemplu, pe rândul 8 al unei piramide, se află 27 = 128 de buline de ciocolată. Pe fiecare rând al unei piramide se află unul sau mai multe tipuri de buline, iar același tip de buline se poate folosi pe oricâte rânduri. Dintre piramidele care se pot forma, cele serioase conțin pe fiecare rând doar un tip de buline. Folosind toate bulinele, ajutați-o pe Andra să determine:

1) Numărul minim de piramide de ciocolată pe care le poate forma.
2) Numărul minim de piramide serioase de ciocolată pe care le poate forma, astfel încât toate cele obținute să fie de acest fel.
