Problem 1. (50 points) Here are two possible algorithms for computing MST. The input of these algorithms is a connected and undirected graph G=(V,E) that is edge weighted by . The output is a set of edges TE. For each algorithm, you need to determine whether the possible MST algorithm works, i.e., returns an MST for G. If you determine it works, then show the correctness of the algorithm. Otherwise, show that the algorithm does not compute a MST. \begin{tabular}{l} \hline Algorithm 1 PossiblE-MST-1 (G,w) \\ 1: sort the edges in nonincreasing order based on their weight \\ 2: TE \\ 3: for each edge e, obtained in nonincreasing oreder by weight do \\ 4: if T{e} is a connected graph then \\ 5: TT{e} \\ 6: return T \\ \hline \end{tabular} \begin{tabular}{l} \hline Algorithm 2 Possible-MST-2 (G,w) \\ \hline 1: T \\ 2: for each edge e, obtained in arbitrary order do \\ 3: if there is no cycle in T{e} then \\ 4: TT{e} \\ 5: return T \end{tabular}
