The following is definition of Binary Search Tree(BST) according to Wikipedia Binary Search Tree, is a node-based binary tree data structure which has the following properties: The left subtree of a node contains only nodes with keys lesser than the node’s key. The right subtree of a node contains. Find more on Program to insert and delete a node from the binary search tree Or get search suggestion and latest updates.

In this tutorial we will see what is binary search tree, binary search tree definition, c program for binary search tree. Binary search tree definition. Binary search tree (BST) is a binary tree in which each node has value greater than every node of left sub tree and less than every node of right subtree. Binary search tree complexity: O(log N).

Nice post. Just a suggestion. I believe, finding a minimum value in a BST doesn't have to traverse the right subtree. Minimum value must be either on the left subtree or node itself(in case if left subtree is null). Function find_minimum_value can be optimized if right subtree traversal is removed.

In C, you can cast the pointers in the tree to intptr_t type and perform bitwise operations to them.

As you traverse down the tree, you can store the 'parent' pointer of a node by xoring it with the pointer you traversed with. You can then traverse back up the tree by xoring the the address of the node you are coming from with the modified pointer.

A worked example of this traditional technique is at http://sites.google.com/site/debforit/efficient-binary-tree-traversal-with-two-pointers

Given the ability to traverse the tree without recursion, you can then create iterative versions of any of the algorithms based on traversing the tree.

 Skilled Ist class  Skilled IInd class  Unskilled Labour charges can be obtained from Schedule of Rates. •  Labour: May be classified into three types.  To revise the schedule of rates due to increase in the cost of material and labour or due to change in technique. Building and engineering contracts by b s patil pdf merge.  Lead Statement:The distance between the source of availability of material and construction site is known as Lead and is calculated in km.The conveyance cost of material depends on lead  The lead statement will give the total cost of materials per unit item including first cost, conveyance loading-unloading, stacking charges etc. 30% of the skilled labour in data should be taken as Ist class and remaining 70% as IInd class.

# include <conio.h>

intdata;

}node;

voidinsert(node *,node *);

voidpreorder(node *);

node *search(node *,int,node **);

voidmain(){

charans='N';

node *new_node,*root,*tmp,*parent;

root=NULL;

do{

printf('n2.Search');

printf('n4.Exit');

scanf('%d',&choice);

switch(choice){

printf('nEnter The Element ');

if(rootNULL)

else{

inorder(root);

preorder(root);

postorder(root);

break;

}while(choice!=4);

node *temp;

temp->lchild=NULL;

returntemp;

This function is for creating a binary search tree

voidinsert(node *root,node *new_node){

if(root->lchildNULL)

else

}

if(new_node->data>root->data){

root->rchild=new_node;

insert(root->rchild,new_node);

}

This function is for searching the node from

node *temp;

while(temp!=NULL){

printf('nThe %d Element is Present',temp->data);

}

temp=temp->lchild;

temp=temp->rchild;

returnNULL;

This function displays the tree in inorder fashion

voidinorder(node *temp){

inorder(temp->lchild);

inorder(temp->rchild);

}

This function displays the tree in preorder fashion

voidpreorder(node *temp){

printf('%d',temp->data);

preorder(temp->rchild);

}

This function displays the tree in postorder fashion

voidpostorder(node *temp){

postorder(temp->lchild);

printf('%d',temp->data);

}

Explanation :

get_node() function will allocate memory dynamically and allocate one node.
if below condition is satisfied then we can say that we are going to create first node of the tree. (i.e Tree is empty and this created node is very first node)

If condition does not satisfied then we can say that we have already node in a tree. (i.e this node which we have created is not a first node)

Display Tree

To display tree we have 3 traversal Techniques –

In-Order Traversal
Pre-Order Traversal
Post-Order Traversal

Algorithm for Preorder Traversal of Binary Search Tree :

{

then

else

Go toLeft Childof node

}

Similarly Post order and inorder traversal works.
