Provide tags and a correct Python 3 solution for this coding contest problem. Devu is a dumb guy, his learning curve is very slow. You are supposed to teach him n subjects, the ith subject has ci chapters. When you teach him, you are supposed to teach all the chapters of a subject continuously. Let us say that his in...
