# --description--

Given a contrast ratio and a boolean indicating whether the text is large, return the WCAG rating using the following table:

| Rating | Normal Text | Large Text |
|--------|-------------|------------|
| `"AAA"` | 7.0+ | 4.5+ |
| `"AA"` | 4.5+ | 3.0+ |
| `"Fail"` | below 4.5 | below 3.0 |

# --hints--

`getContrastRating("7.5", false)` should return `"AAA"`.

```js
assert.equal(getContrastRating("7.5", false), "AAA");
```

`getContrastRating("4.8", false)` should return `"AA"`.

```js
assert.equal(getContrastRating("4.8", false), "AA");
```

`getContrastRating("4.2", false)` should return `"Fail"`.

```js
assert.equal(getContrastRating("4.2", false), "Fail");
```

`getContrastRating("4.5", true)` should return `"AAA"`.

```js
assert.equal(getContrastRating("4.5", true), "AAA");
```

`getContrastRating("3.0", true)` should return `"AA"`.

```js
assert.equal(getContrastRating("3.0", true), "AA");
```

`getContrastRating("2.7", false)` should return `"Fail"`.

```js
assert.equal(getContrastRating("2.7", false), "Fail");
```

# --solutions--

```js
function getContrastRating(ratio, isLargeText) {
  if (isLargeText) {
    if (ratio >= 4.5) return "AAA";
    if (ratio >= 3.0) return "AA";
  } else {
    if (ratio >= 7.0) return "AAA";
    if (ratio >= 4.5) return "AA";
  }
  return "Fail";
