The question is: When x and y are two positive integers, x > y, a Pythagorean Triple, (a, b, c), has the form: a = x^2-y^2, b = 2xy, c = x^2 + y^2. Determine the 16 unique Pythagorean Triple, (a, b, c), with a, b, and c less than 100.

Note: (3, 4, 5) and (6, 8, 10) are the same Pythagorean Triple.

Btw, it would be awesome if you could tell me how to do it as well as the answer.
Thank you in advance! :D
