--description--

Let us call an integer sided triangle with sides a ≤ b ≤ c barely acute if the sides satisfy a2 + b2 = c2 + 1.

How many barely acute triangles are there with perimeter ≤ 25,000,000?

--hints--

euler223() should return 61614848.

assert.strictEqual(euler223(), 61614848);

--seed-contents--

function euler223() {

  return true;
