Hi, here's your problem today. This problem was recently asked by Facebook:
You are given a list of numbers, and a target number k. Return whether or not there are two numbers in the list that add up to k.
Example:
Given [4, 7, 1 , -3, 2] and k = 5,
return true since 4 + 1 = 5.
Try to do it in a single pass of the list.
