[game-tree] In the game tree show below, the first level is a MAX level, the second is a MIN level, the third is a MAX level and the fourth is a MIN level. Each leaf-node shows its value for MiniMax search, and each node is labeled (from left to right) as L1, L2, ... Apply alpha-beta search to the tree. Some leaves need not be evaluated (to be pruned). After processing all the nodes below, what would be the alpha value or beta value of the node (that is, the parent of L1 to L4) shown below for alpha and beta values? Beta is 10 Beta is 11 Beta is positive infinity Beta is negative infinity Beta is positive Beta is negative
