With ROOTS AND LEAVES of a graph, focus on matrices and directed graphs represented as adjacency matrices using MATLAB.

Taking an adjacency matrix as input (matrix in MATLAB, 2d array in C++), return the set of roots and leaves in the graph. For example, in the graph below, the graph has roots 1,2 and leaf 7. It is possible for a graph not to have roots and/or leaves. Taking an adjacency matrix as input (matrix in MATLAB, 2d array in C++), return the set of roots and leaves in the graph.
