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.
