Given a set of integer sets S, find the smallest possible set of integers X so that every set in S contains at least one
This might help you Look at a question in cs.stackexchange, it seems this question is asked there.This is actually a Hitting Set problem. It is formally a NP hard problem, but given some info about the expected input, some tweaks are usually possible

Why is the Big-O complexity of this algorithm O(n^2)?
I hope this helps . During every iteration you increment i and decrement j which is equivalent to just incrementing i by 2. Therefore, total number of iterations is n^2 / 2 and that is still O(n^2).
