--description--

Consider the triangle with sides √5, √65 and √68.

It can be shown that this triangle has area 9.

S(n) is the sum of the areas of all triangles with sides √(1+b2), √(1+c2) and √(b2+c2) (for positive integers b and c ) that have an integral area not exceeding n.

The example triangle has b=2 and c=8.

S(106)=18018206.

Find S(1010).

--hints--

euler390() should return 2919133642971.

assert.strictEqual(euler390(), 2919133642971);
