/*
Solution: Sort the weights, and take all of the largest ones until the sum >= l. To check if it's possible, take the
same # of elements, but all the smallest ones now. If the smallest sum <= u, then it's possible.
Now, start with all the largest weights, and move one at a time down to the smallest ones. You'll step by no more than
w_max - w_min, which means you'll step no more than u-l, so you'll hit the target range eventually.
Runtime: O(N * log(N))
