There are N different flavors that you can prepare, and each flavor can be prepared “malted” or “unmalted“. So, you can make 2N different types of milkshakes. Each of your customers has a set of milkshake types that they…

    Hey there, since things are getting a little more calm, I can focus once more to solve some nice Code Jam problems. And here we go, from the first official tournament round: Problem A: Minimum Scalar Product. It says: You are given two vectors v1=(x1,x2,…,xn) and v2=(y1,y2,…,yn). The scalar product of these vectors is a…
