Description

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

How many barely obtuse triangles are there with perimeter ≤ 75,000,000?

tests:
  - text: <code>euler224()</code> should return 4137330.
    testString: assert.strictEqual(euler224(), 4137330);

function euler224() {
  // Good luck!
  return true;
}

euler224();

// solution required
