#4203
NumberOfPoints
În planul xOy
se găsesc n
puncte de coordonate numere naturale, nu neapărat aflate pe poziții distincte. Pentru fiecare punct din plan de coordonate (x, y)
trebuie să spuneți câte alte puncte au coordonatele (p, q)
cu proprietatea că 0 ≤ p < x
și 0 ≤ q ≤ y
(atenție, p
este strict mai mic decât x
, iar q
este mai mic sau egal cu y
).
