Unformatted text preview: the remainder as bad guys such that each rivalry is between a good guy and a bad guy. If it is possible to perform such a designation, your algorithm should produce it. (Hint: figure out how to use BFS to solve this problem.) 3. (1 Point) p.547: 22.31 Make a 3by3 chart with row and column labels WHITE, GRAY, and BLACK. In each cell ( , ) i j , indicate whether, at any point during a depthfirst search of a directed graph, there can be an edge from a vertex of color i to a vertex of color j . For each possible edge, indicate what types it can be. 4. (1 Point) p.547: 22.32 Show how depthfirst search works on the graph of Figure 22.6 (p.548). Assume that the for loop of lines 57 of the DFS procedure considers the vertices in alphabetical order, and assume that each adjacency list is ordered alphabetically. Show the discover and finishing times for each vertex, and show the classification of each edge. 1...
