How binary search tree can be stored in the memory?
Each node of the tree contains three cells. The first cell contains the data to be stored; the second cell contains a pointer to the first cell’s left child, and the third cell contains a pointer to the first cell’s right child. A value of 00 as a pointer represents the nil pointer.
How Binary trees are represented in memory?
Binary trees in linked representation are stored in the memory as linked lists. These lists have nodes that aren’t stored at adjacent or neighboring memory locations and are linked to each other through the parent-child relationship associated with trees.
Does a binary search tree need to be complete?
A binary tree is considered full if every node has exactly 0 or 2 children. A binary tree is considered complete if every level is full except the last, and all nodes are pushed as far left as possible. So if it fits both of these descriptions, which is possible, it can simultaneously be full and complete.
What are the conditions for an optimal binary search tree?
10. What are the conditions for an optimal binary search tree and what is its advantage? Explanation: For an optimal binary search The tree should not be modified and we need to find how often keys are accessed. Optimal binary search improves the lookup cost.
How can you traverse a binary tree?
There are basically three traversal techniques for a binary tree that are, Preorder traversal. Inorder traversal. Postorder traversal….1) Preorder traversal
- Visit the root.
- Traverse the left sub tree of root.
- Traverse the right sub tree of root.
Which of the following is incorrect with respect to binary tree?
Which of the following is incorrect with respect to binary trees? Explanation: In a binary tree, there are atmost 2k nodes in level k and 2k-1 total number of nodes. Number of levels is at least ceil(log(N+1)). 11.
In what respect is the optimal binary search tree better than the binary search tree?
The time required to search a node in BST is more than the balanced binary search tree as a balanced binary search tree contains a lesser number of levels than the BST. There is one way that can reduce the cost of a binary search tree is known as an optimal binary search tree.
