Can you tell me how to solve it?

4 Alpha-Beta Pruning ODOB DDD Figure 3: Alpha-Beta Pruning (a) Please fill in the state's utility values for the game tree above using alpha-beta pruning, cross the pruned edges and write down the Alpha Beta value from the parent state to the child state. You don't need to write Alpah-Beta values for the edges that have been pruned and the utility values for the pruned states. N.B.: The numbers in the edges are just identifiers, as shown in the following table. Please fill in the corresponding Alpha Beta values in the table for each edge.
