I am to write a code for a colision detection where it detects whether two 3D spheres are colliding. Each 3D sphere has a center (an x, y, z coordinate) and a radius. Two spheres are colliding if the distance between their two centers is less then or equal to the sum of their radii. The distance D between 2 spheres with centers (x1, y1, z1) and (x2, y2, z2) is given by the formula:
D = √[(x₂ - x₁)² + (y₂ - y₁)² +(z₂ - z₁)²]

I need to define a class Sphere and create two sphere objects and initialize them with user inputs. I also need to use the == operator to compare the two spheres. I need to display a message of if they are colliding nad if they are not colliding.

Thank you.
