Two_Circles_Central_Coordinate.py

'''There are two circles C1 with radius r1, central coordinate (x1, y1) and C2 with radius r2 and central 
coordinate (x2, y2)'''

# Write a Python program to test the followings -
# - "C2 is in C1" if C2 is in C1
# - "C1 is in C2" if C1 is in C2
# - "Circumference of C1 and C2 intersect" if circumference of C1 and C2 intersect, and
# - "C1 and C2 do not overlap" if C1 and C2 do not overlap.

'''Input: Input numbers (real numbers) are separated by a space.'''
