Given a graph $\backslash ($ G$=($V$,$ E$)\backslash ),$ the breadth$-$first ranking of vertices of $\backslash ($ G $\backslash )$ are the values assigned to the vertices of $\backslash ($ V $\backslash )$ in a breadth$-$first traversal of $\backslash ($ G $\backslash )$ from a node $\backslash ($ v $\backslash ).$ Show how the breadth$-$first ranking of vertices of $\backslash ($ G $\backslash )$ can be performed on a p$-$process mesh.
