#4619

Alex este un băiat căruia îi place să citească și care contorizează cât de mult a citit pe parcursul ultimelor n zile. Mai precis, el și-a notat câte pagini a citit în fiecare dintre acestea. Chiar dacă pasiunea lui este literatura, își dorește să progreseze și la informatică. Alex și-a pus două întrebări legate de șirul format din numărul de pagini citite de el în ultimele n zile, dar după ce a petrecut câteva zile gândindu-se la ele și-a dat seama că sunt prea dificile pentru el. Ajutați-l să găsească răspunsurile! Fie numărul n, numărul p și acel șir de valori notate de Alex în cele n zile. Determinați răspunsul la următoarele întrebări care îl frământă pe Alex:

1) Câte triplete de numere aflate pe poziții consecutive în șirul dat îndeplinesc condiția ca cel mai mare divizor comun al lor să aibă cel mult p divizori naturali?
2) Care este lungimea maximă a unei secvențe din șirul dat, în care cel mai mare divizor comun al oricărui triplet de numere situate pe poziții consecutive are cel mult p divizori naturali?
