Web3 Answers. Even & odd refer to the symmetry around n = 0. Even means x [ n] = x [ − n]; you can get the part for n < 0 by simply mirroring the part for n > 0 at the n = 0 line. Odd means x [ n] = − x [ − n]; you can get the part for n < 0 by simply mirroring the part for n > 0 at the n = 0 line and multiplying it by − 1. WebDFT(Graph g): let startVertex be any vertex in g DFTr(g, startVertex) DFTr(Graph g, Vertex v): visit(v) for each vertex w such that the edge v → w exists: DFTr(g, w) DFT is the complete algorithm; it's job is to traverse an entire graph. DFTr can be seen as a recursive algorithm to do a partial traversal of all of the vertices that can be ...
