TOPOLOGICAL SORT Consider the following graph (a) Suppose we run the topological

Consider the following graph (a) Suppose we run the topological sort algorithm on this graph. List three different possible valid outputs. (b) Suppose we want to modify this graph so that running topological sort is impossible -so that there is no valid output when we try running the algorithm. We are allowed to change the graph by either adding or removing exactly one edge. What edge would you add or remove? Briefly explain why your change causes the graph to no longer have a valid topological ordering
