WebDescription. A weight-balanced tree is a binary search tree that stores the sizes of subtrees in the nodes. That is, a node has fields key, of any ordered type; value (optional, only for mappings); left, right, pointer to node; size, of type integer.; By definition, the size of a leaf (typically represented by a nil pointer) is zero. The size of an internal node is the sum of … WebAn obvious way to find an optimal binary search tree is to generate each possible binary search tree for the keys, calculate its weighted path length, and keep that tree with the smallest weighted path length. This search through all possible solutions is not feasible except for small n,
