Let G be a connected edge-weighted graph with n vertices and m edges. Let e₁ and e2 be two edges in G where e₁e2. Denote by T(e₁, e2) a spanning tree of G that has minimum cost among all spanning trees of G that contain both e₁ and e2. (a) Design an O(n²) time algorithm to find T(e₁, e2) for a given e₁, e2 € E(G). (b) Design an O(m log n) time algorithm to find T(e₁, e2) for a given e₁, €2 € E(G).
