Driver Program to Test Tree in JAVA

Driver Program to Test Tree:-

A basic driver program to test all the functions that i will posting in my blogs using this sample tree.







package com.BST;

public class BSTOperation {

 /**
  * @param args
  */
 public static void main(String[] args) {
  
  BinarySearchTree btree=new BinarySearchTree();
  btree.inorder(btree.root);
  Node node1=new Node(8);
  Node node2=new Node(3);
  Node node3=new Node(1);
  Node node4=new Node(6);
  Node node5=new Node(4);
  Node node6=new Node(7);
  Node node7=new Node(10);
  Node node8=new Node(14);
  Node node9=new Node(13);
  
  btree.root=btree.insert(node1, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node2, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node3, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node4, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node5, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node6, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node7, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node8, btree.root);
  btree.inorder(btree.root);
  System.out.println("");
  btree.root=btree.insert(node9, btree.root);
  System.out.println("Inorder");
  btree.inorder(btree.root);
  System.out.println("");
  System.out.println("post order");
  btree.postOrder(btree.root);
  System.out.println("");
  System.out.println("pre order");
  btree.preOrder(btree.root);
 }

Insertion Sort in JAVA

What is insertion sort?

It is a sorting technique that is based on the partitioning of array into two parts like selection sort, sorted and unsorted.

The process is:-

compare adjacent elements.
if(left > right)
Swap the element
{
check for sorted array whether it is still in sort manner(put j=i and loop in until j is not equal to zero)
- No
check for if(right<left)
swap
do it until at the end of position.
}

Implementation:-

Underline eleemnts are part of sorted arrayinside main array loop 142710333519424 (141027333519424 (here sorted array is distorted hence sorting has been done inside the loop) inside sorted array loop101427333519424 inside main array loop101427333519424 inside main array loop 101427333519424 inside main array loop101427333519424 inside sorted array loop 101427193335424 inside sorted array loop 101419273335424 inside main array loop 101419273335424 inside main array loop 101419273335424 inside sorted array loop101419273343542 inside…
