find the cheapest combination
greedy algorithm is not optimal
Lying in bed last night, I awoke with a realization that my naive algorithm does not work. My original greedy polynomial solution is not optimal. The original unit test made the invalid assumption if we sort the bundles by value, we will always find the largest discount. This is clearly not true given a bundle can be used more than once.
In this above case (which I wrote down on my iPad last night), we should find a discount of $6, but the current algorithm will find a discount of $2. Unhappy customer.
Looks like I just bought myself some work this weekend! :-)
