Question
In a weight-balanced tree, a new node with a large weight is inserted as the right child of a node with a small weight.How might the tree adapt to maintain balance, and what rotation operation is likely to be involved?a)No action is needed.b)The left subtree's weight increases; left rotation is performed.c)The right subtree's weight increases; right rotation is performed.d)The left subtree's weight decreases; double rotation is performed.
Solution
c) The right subtree's weight increases; right rotation is performed.
When a new node with a large weight is inserted as the right child of a node with a small weight, the weight of the right subtree increases. This disrupts the balance of the tree. To restore balance, a right rotation operation is likely to be performed. This operation shifts the node with the smaller weight up and to the right, and the node with the larger weight down and to the left. This helps to redistribute the weights and maintain the balance of the tree.
