Perform alpha$-$beta pruning on the tree below using a depth$-$first search; in the case of multiple children, expand the left$-$most remaining child first. Assuming we use the variable v to represent the value currently assigned to the node, list the alpha$(\backslash$alpha $),$ beta $(\backslash$beta $)$ and value $($v$)$ variables of each node as $(\backslash$alpha $,$ v$,\backslash$beta $).$Use the table to help you keep track of the current $(\backslash$alpha $,$ v$,\backslash$beta $)$ state of each node. So$,$ the $(\backslash$alpha $,$ v$,\backslash$beta $)$ state at the bottom of each row represents the current state of that node. Values in the same row have no meaning...the most important thing is that each value on the bottom of each column represents the current $(\backslash$alpha $,$ v$,\backslash$beta $)$ values for that state upon completion of the search.

When alpha$-$beta pruning determines that you can prune certain nodes, then draw an $$X$$ over the successor edge $($not individual nodes$)$ in the figure above that gets pruned.
