5-8. [3] Present correct and efficient algorithms to convert an undirected graph G be- tween the following graph data structures. You must give the time complexity of each algorithm, assuming n vertices and m edges. (a) Convert from an adjacency matrix to adjacency lists. (b) Convert from an adjacency list to an incidence matrix. An incidence matrix M has a row for each vertex and a column for each edge, such that M[i,j] = 1 t vertex 2 is part of edge J, otherwise M [23] = 0. (c) Convert from an incidence matrix to adjacency lists
