\item \self  Construct a Reduced Ordered Binary Decision Diagram (ROBDD) for the formula 
$$f = (\lnot x \lor \lnot y) \land (x \land (y \lor z)),$$

using \textit{variable order} $y < z < x$. Use complemented edges and a node for \texttt{true} as the only constant node. To simplify drawing, you may assume that \textit{dangling edges} point to the constant node. Write down all cofactors that you compute to obtain the final result and mark them in the graph.

% (not x or not y) and (x and (y or z))
