representations better. Suppose we have a graph with 4 vertices (0, 1, 2, 3). There are edges between 0 and 1, 0 and 2, and 1 and 2. In an adjacency matrix representation, we would have a 4x4 matrix (since there are 4 vertices), where the cell at the ith row and jth column would be 1 if there is an
