"""Find the only Pythagorean triplet, {a, b, c}, for which a + b + c = 1000.

A Pythagorean triplet is a set of three natural numbers, a b c, for which,
|
|
a2 + b2 = c2
|
|
For example, 32 + 42 = 9 + 16 = 25 = 52.

|

There exists exactly one Pythagorean triplet for which a + b + c = 1000.

Find the product abc.
