• A: Pairsumonious Numbers

If you've already solved one or more of these problems, try (1) solving again without referring to your old solution, and/or (2) using a different language (Java or C++). If you want to work on an additional problem from this chapter, let me know.

Hints:

• A: For Pairsumonious Numbers, you'll need to store the N*(N-1)/2 values into a sorted array to use them to compute the N sums. This problem gets you set up for that.
