# Binary search tree traversal in c program

November 18, by Mohamed Sanaulla 28 Comments. Most of the students fresh out of their engineering studies or those who are still studying will have the concept of Binary Search Trees fresh in their minds.

But with most of the people who have been out of college for many years now will kind of be having a not so clear idea of Binary Search trees unless they have been using it or related concepts at their work. Also you can read the extensive concepts about this topic on any of the popular data structure book in the store.

In this tutorial I would show how to implement a Binary Search Tree BST in Java and also show the following operations: Binary Search Tree BST is a binary tree data structure with a special feature where in the value store at each node is greater than or equal to the value stored at its left sub child and lesser than the value stored at its right sub child.

Lets look at an example of a BST:. In the above example you can see that at each node the value in the left child is lesser than or equal to the value in the node and the value in the right child is greater than the value in the node.

Now that we have seen how a BST looks, let me show you how one can build a BST and insert nodes into the tree by implementing the algorithm in Java. The basic idea is that at each node we compare with the value being inserted. If the value is lesser then we traverse through the left sub tree and if the value is greater we traverse through the right subtree.

Suppose we have to insert the value 64 in the above BST, lets look at the nodes traversed before its inserted at the right place:.

If you have noticed in the above example that the leftmost node has the lowest value and the rightmost node has the highest value. This is due to the sorted nature of the tree. Using this principle the below methods return us the lowest and highest value in the Binary Search Tree:.

Traversing the tree or BST in this case is visiting each of the nodes present in the tree and performing some operation with the value present in the node which in this case will be printing the value present in the node.

Visiting the right and left sub tree will be a recursive operation. The order in which we perform the three operations i. In this should i buy a timeshare in aruba the left sub tree of the given node is visited first, then the value at the given node is printed and then the right sub tree of the given node is visited.

This process is applied recursively all the node in the tree until either the left sub tree is empty or the right sub tree is empty.

Applying the Inorder traversal for the give example we get: In this traversal the value at the given node is printed first and then the left sub tree of the given node is visited and then the right sub tree of the given node is binary search tree traversal in c program. Applying the Preorder traversal for the give example we get: In this traversal the left sub tree mbt trading forex autotrader the given node is traversed first, then the right sub tree of the given node is traversed and then the value at the given node is printed.

Applying the Postorder traversal for the give example we get: The complete code which builds the tree for the example explained in this code and prints the maximum, minimum value, inorder traversal, preorder basics of binary option system z906 and **binary search tree traversal in c program** order traversal can be found below:.

In this tutorial you would have got the very clear understanding on how to implement the Binary Search Tree BST in Java with various emerging currency international traders. We have done good enough research on the binary search trees concept before writing this tutorial.

Right now I am looking for similar stuff on Data Structure in java. Have you post any such more blogs on graph,m tree, and other important Algorithms of data structure. Glad to know that this post has helped you.

We will work on few more post on this data structure. Could you suggest any specific post on this subject?
