English 3rd EditionWhile reading recently, feel some practice lack of reference, so according to the partial summary of their own answers, but also to strengthen the learning process.If there is any shortage or doubt, please correct me.Exercises 22.5-1How can the number of strongly connected components of a graph change if a Newedge is added? Each strongly connected component can be treated as a vertex, a str

lightest edge is unique across the cut (S, v-s). Both E and X are the same edge. So e also belongs to T ', because we choose E to be arbitrary, all sides in T, likewise in t '. The smallest spanning tree is unique. The exchange of conditions and conclusions is not tenable, as follows.Exercises 23.1-7argue that if all edge weights of a graph is positive, then any subset of edges the connects all vertices and have minimu M total weight must is a tree.Give An example to show that the same conclusi
