What is the time complexity to delete the root of a minimum-level BST with n nodes? Explain.
Homework Answers
Solution:
BST stands for binary search tree.
The time complexity of deleting the root of minimum level BST with n nodes is O(log n).
Deletion of any node in BST is an iterative process and it involves the below given two steps:
- First step is getting the root node.
- The next step is to pick one of the child elements and replacing the child nodes.
Repeating the above two steps until we reach on the leaf node.
Thus, time complexity for getting a root node is O(n).
Time complexity for getting a child node is O(n)
Repeating the above process till we reach the leaf node.

Find the median in a given BST with n nodes. The code should take O(H) time, where is the height of the BST. You can assume that the size of the tree is an odd number. Describe your idea in short sentences below? Provide the code that finds the median in the BST and rune to see if it works.

In general, assuming a balanced BST with n nodes (A balanced binary tree has roughly the same number of nodes in the left and right subtrees of the root), what is the maximum number of operations required to search for a key? Please notice that the tree in this exercise is not balanced. Trace the algorithm for creating a parse tree for the expression (((4 x 8)/6)–3 Please help me understand :(

The INORDER traversal output of a binary tree is U,N,I,V,E,R,S,I,T,Y and the POSTORDER traversal output of the same tree is N,U,V,R,E,T,I,S,I,Y
a. The INORDER traversal output of a binary tree is U,N,I,V,E,R,S,I,T,Y and the POSTORDER traversal output of the same tree is N,U,V,R,E,T,I,S,I,Y. Construct the tree and determine the output of the PREORDER traversal output. b. One main difference between a binary search tree (BST) and an AVL (Adelson-Velski and Landis) tree is that an AVL tree has a balance condition, that is, for every node in the AVL tree, the height of the left and right subtrees differ by at most 1....
