Write a program that will determine whether four side lengths entered by the user could form a polygon (closed sided figure). All the following must be true for the side lengths to be a polygon:

a

b

Next, if a polygon can be formed, determine whether it can form a rectangle, and then a square. Output a message that states whether or not a polygon can be formed and, if one can be formed, whether a square or rectangle can be formed.

Execute this program twice using values of:

15, 2, 4, 3

5, 3, 3, 5
