= Let G be a connected undirected graph on n vertices. We say that two distinct spanning trees T and S of G are one swap away from each other if |TS| -2; that is, T and S differ in only one edge. For two distinct spanning trees T and S we say that R₁, R₂, ..., Rk form a swapping sequence from T to S if: 1. R₁ = T, 2. Rk = S, and 3. for any 1 < i <k, the trees R; and R₁+1 are one swap away from each other Your task is to design a polynomial time algorithm that given G and two spanning trees T and S of G, constructs a minimum length swapping sequence. Remember to: a) Describe your algorithm in plain English. b) Prove the correctness of your algorithm. c) Analyze the time complexity of your algorithm.
