## Instructions
Write a function to check if an array contains a particular number.

### Examples
```
check([1, 2, 3, 4, 5], 3) ➞ true

check([1, 1, 2, 1, 1], 3) ➞ false

check([5, 5, 5, 6], 5) ➞ true

check([], 5) ➞ false
```

### Notes
- Don't forget to `return` the result.
- If you get stuck on a challenge, find help in the **Resources** tab.
- If you're *really* stuck, unlock solutions in the **Solutions** tab.
