write the algorithm to draw a sphere, the function should have parameters
1. diameter (how many line)
2. character (use which character to draw)
eg, draw_sphere(10, '8') will produce:
Code: Select all
88888
8888888888888
8888888888888888888
888888888888888888888
88888888888888888888888
88888888888888888888888
888888888888888888888
8888888888888888888
8888888888888
88888
the above is a sphere of 10 lines, which is drawn using the character "8"
