The Sum of all fears coding challenge is intended to assess a candidate’s ability to work with Arrays.

Given a list of numbers and a number K, return whether any two numbers from the list add up to K. Example: given [10, 15, 3, 7] and K of 17, return true since 10 + 7 is 17. The basic challenge is to write a program that uses a hard-coded array of [10, 15, 3, 7] and allows the user to enter a value for K before running the algorithm and returning true or false.
