Can someone please explain how to solve this question ?

Given a continuous plane, there are N circles each having coordinate like (c_ix, c_iy) and radius r_i. Given a rectangle( the rectangle has length parallel to x-axis and breadth parallel to y-axis) having top-left corner as P1(p₁x, p₁y) and bottom-right corner as P2(p₂x, p₂y). Tell if it is possible( true or false ) to travel from P1 to P2 without touching or crossing the circles while being inside the rectangle.

NOTES:

• The coordinates are NOT necessarily integer coordinates.
• The trajectory of travel from P1 to P2 may not necessarily be a straight line, it can be anything (think of it like a river).
