# --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?
|
|
|

# --hints--

|
|
`euler224()` should return 4137330.
|
|
|
|
```js
|
|
assert.strictEqual(euler224(), 4137330);
|
|
```
