Problem 1 Consider the directed graph given by V={0, 1, 2, 3, 4, 5), E={[0,2], [0,3], [0,4], [2,1], [2,4], [3,5], [4,0]}. Determine the vertex visitation order that results from breadth-first traversal starting first from vertex 2 then vertex 3, 4, and 5. Use the breadth-first search function shown below. See class12_graph1 handout.pdf for layout details. Assume all vertex colors are reset to WHITE before any run. Process lowest numbered vertex first in case of a tie. Instead of producing lots of arrays that indicate when the color is changed for which vertex, draw trees that represent the traversal process. Then extract the corresponding vertex visitation order. void graph::bfsearch(int source) { queue Q; Q.push(source); Source = 0 PD Sourial while (!Q.empty()) { int i=0.front (); Q.pop(); if (vcolor[i] == BLACK) continue; vcolor[i] = BLACK; for (int k=0; k
