"Web3. [8 marks] Let G = (V, E) be an undirected weighted graph with positive weights of edges. Assume you are given a minimum-weight spanning tree T in G (for example you called Prim's or Kruskal's algorithm). One edge e = (u, v) changes its weight and we want to update the minimum spanning tree. There are 4 cases. " - Minimum cycle in undirected graph
