title: Bin Packing or Knapsack?
body: <p>I'm having some issues with an assignment I have. I've been searching stackoverflow and other websites to see which kind of problem I'm dealing with, and turns out I'm not sure if it's a knapsack problem or a bin packing problem. Here's the problem:</p>
  <p>An old lady bought N products, each product with a different weight (kg), and she wants to fit it all into a bag that can hold K kg. Find the set of objects that the sum of the weights gets as close as it can to K.</p>
