#2443

Se consideră un șir de numere naturale nenule a[1], a[2], …, a[n]. Asupra șirului se efectuează Q interogări. Fiecare interogare este dată de o pereche (x, s): care este indicele maxim p cu proprietatea că a[i] ≤ x, pentru orice i=1..p și în plus a[1] + a[2] + ... + a[p] <= s?
Trebuie să răspundeți la fiecare din cele Q întrebări.
