(iii) Given below is the Kruskal Algorithm to find the minimum spanning tree. What is the time complexity of this algorithm using a sorting algorithm in the worst case scenario? How can you improve this algorithm for an average or best case scenario? (10 Marks) G=(X.U) G=(X', U') where X'= X.U' = 0 Sort all arcs EU in increasing order. For each arcu EU Do If U' U {u} does not contain a cycle Then U'U'U{u} Endif EndFor
