Cerc3
Se consideră pe axa Ox
din plan n puncte distincte reprezentând centrele a n
cercuri numerotate cu numerele distincte de la 1
la n
. Pentru fiecare cerc k
se cunosc abscisa x
k
a centrului său şi raza sa r
k
.
Să se scrie un program care să determine numărul y
maxim de cercuri exterioare două câte două dintre cele n
.
