Question
In a weight-balanced tree, the _____ of a node is defined as the number of nodes in its left subtree divided by the number of nodes in its right subtree.a)rotation factorb)constant factorc)depth ratiod)weight balance factor
Solution
The answer is d) weight balance factor. In a weight-balanced tree, the weight balance factor of a node is defined as the number of nodes in its left subtree divided by the number of nodes in its right subtree. This factor is used to maintain the balance of the tree during insertions and deletions. If the weight balance factor is not within a certain range, the tree is re-balanced using rotation operations.
