#### Two Elements Add Up to Argument

You are given an array of integers and an integer K as arguments. Return true if exactly two elements from the array will add up to the integer K, false if not.

### Requirements

- Must return either true or false

#### Example #1

```
solve([10,12,3,4,5], 8)
> true
```

*3 and 5 added together equals 8, so we return true.*

#### Example #2

```
solve([-10,12,17,14,15], 3)
> false
```

*No pair of integers in this array will sum to 3, so we return false.*
