Problem 4. (12 marks) Consider an edge weighted connected graph G

Problem 4. (12 marks) Consider an edge weighted connected graph G = (V, E) with edge weights w (u, v) for each edge (u, v) e E, and a MST of the graph, T. Suppose a new edge (u*, v*) E with weight w(u*, v*), where uk, u* e V, is added to the graph. Describe a procedure that would find the new MST of the revised graph. Your algorithm must run faster than recomputing the MST from scratch, i.e., must run in o E log |V]). Analyze the running time of your procedure
