Take 8 integer inputs; say X1, Y1, X2, Y2, X3, Y3, X4, Y4. Determine whether these inputs form a rectangle, a square or neither in coordinate plane. Assume that two consecutive inputs form a coordinate point (x, y). If the points form a rectangle or a square then output name of shape with its perimeter.
Sample Input
Sample Output
(0,0) (0,0) (0,0) (0,0)
The points given forms a square with perimeter 0 units
(0,0) (0,4) (4,0) (4,4)
The points given forms a square with perimeter 16 units
(0,0) (4,0) (0,2) (4,2)
The points given forms a rectangle with perimeter 12 units
(0,0) (0,4) (4,2) (0,1)
The points given neither form a square nor a rectangle.
(3,3) (0,0) (6,0) (3,-3)
The points given forms a square with perimeter 12 units
