Question

Graphs are provided in the input as adjacency matrix. Implement the BFS algorithm in C++ to print the vertices in the BFS order. When there are more than one neighbor, use alphabetical order.

Input Format The first line of input is number of vertices: N The second line is the set of vertices, i.e. vertex names. The next N rows are for the NxN adjacency matrix. Example: 4 A B C D 0 1 1 0 1 0 0 1 1 0 0 1 0 1 1 0 Constraints N is greater than 0 and less than 20. Vertex names are single characters.

Output Format Name of the vertices are printed in the BFS order, starting from the first vertex on the second line of the input. Example: for the above input example A B C D Sample Input 0 4 A B C D 0 1 1 0 1 0 0 1 1 0 0 1 0 1 1 0 Sample Output 0 A B C D Sample Input 1 3 A B C 0 0 1 0 0 1 1 1 0 Sample Output 1 AC B
