What is a drawback of the first approach to balancing a tree?
What is a drawback of the first approach to balancing a tree?
- Inefficient space-wise and time-consuming (correct)
- Requires each node to maintain a reference to its parent
- Automatically re-balances the tree after each operation
- Much less wasteful than the second approach
What does the second approach to balancing a tree require each node to maintain?
What does the second approach to balancing a tree require each node to maintain?
- An efficient algorithm
- An array of aligned nodes
- A sorted structure
- A reference to its parent (correct)
What is a key advantage of the 'self-balancing' tree algorithm?
What is a key advantage of the 'self-balancing' tree algorithm?
- Requires deconstructing and then reconstructing the tree
- Easy to implement and efficient space-wise
- Automatically re-balances the tree after each operation if needed (correct)
- Uses one of the efficient sorting algorithms
