a) [12 pts] Consider the graph below in the following question. If you are iterating over a list of vertices (e.g., neighbors of a vertex), iterate in the alphabetical order. Perform topological sort on this graph, assuming the vertices denote tasks, and the edges represent a "pre-requisite" information. Describe/Show each step clearly. You may either use the forward method (start at a node with no incoming edges), or the backward method (start at a node with no outgoing edges). In any case, make sure to explain it and be consistent. C A E S D B
