Hi. I've just started working on some DP + graph problems recently, but I've gotten stuck on one. It gives you a graph with exactly one simple cycle with no other vertices (all n vertices are on the cycle) and ask you to find the total cost of the maximum independent set of the graph. I know that it is a modification of maximum independent set on trees, but I don't know how to deal with the cycle. The farthest I've gotten is adding the first node as node n+1
