A Binary Search Tree is binary tree which is either empty or a node having a key value, left child & right child.
By analyzing the above definition, we notice that BST comes into two variants namely empty BST & non-empty BST.
The empty BST contain no added structure, whereas the non-empty BST contain three components.
The non-empty BST satisfies the given conditions:
a) The key within the left child of node (if exists) is less than the key in its parent node.
b) The key within the right child of a node (if exists) is greater than the key in its parent node.
c) The left & right sub trees of the root are binary search trees again.
The given are some operations which can be performed on Binary search trees:
A telephone directory having n = 10 records and Name field as key. Let us assume that the names are stored in array 'm' i.e. m(0) to m(9) and the search has to be made for name "X"
Q. How do we represent a max-heap sequentially? Explain by taking a valid example. Ans: A max heap is also called as a descending heap, of size n is an almos
The algorithm to delete any node having key from a binary search tree is not simple where as several cases has to be considered. If the node to be deleted contains no sons,
Write an algorithm in form of a flowchart that takes temperatures input over a 100 day period (once per day) and outputs the number of days when temperature was below 20C and numbe

for i=1 to n if a[i}>7 for j=2 to n a[j]=a{j}+j for n=2 to n a[k]=a[j]+i else if a[1]>4 && a[1] for 2 to a[1] a[j]= a{j]+5 else for 2to n a[j]=a[j]+i ..
Threaded Binary Tree : If a node in a binary tree is not having left or right child or it is a leaf node then that absence of child node is shown by the null pointers. The spac
I need to know about data structure and algorithms. can you help me?
Warnock's Algorithm An interesting approach to the hidden-surface problem was presented by Warnock. His method does not try to decide exactly what is happening in the scene but
