Tree Traversal in JAVA (InOder/preOrder/postOrder)

Tree Traversal in JAVA (InOder/preOrder/postOrder):-

Tree traversal can be done through three ways.

1)Inorder:-

Go recursively to the left node.
Read a node
Go recursively to the right node.

2)Pre Order.

Read a node
Go recursively to the left node.
Go recursively to the right node.


2)Post Order.


Go recursively to the left node.
Go recursively to the right node.
Read a node



public void inorder(Node root)
 {
  
  if(root==null)
  {
  return;
  }
  
  inorder(root.left);
  System.out.print(root.data+",");
  inorder(root.right);
  
  }
 
 public void preOrder(Node root)
 {
  
  if(root==null)
  {
  return;
  }
  
  System.out.print(root.data+",");
  preOrder(root.left);
  preOrder(root.right);
  
  }
 public void postOrder(Node root)
 {
  
  if(root==null)
  {
  return;
  }
  
  postOrder(root.left);
  
  postOrder(root.right);
  System.out.print(root.data+",");
  }

WHAT DOES LOAD BALANCER DO BETWEEN CLIENT COMPUTER AND SERVERS?

Whenever we talk about websites we often tend to be restricted to the domain and hosting only. A person who is generally developing websites does only take care of designing the front end and moreover functionality related to back-end. Most of the  people never thought about the servers and load balancer. Even a student in computer science often confused about the true working of traffic management in servers as well as load balancing it to make sure running the website and application without causing any issue to the end users.
So this article is all about how actually the load balancer work in a real time environment. There are three things that need to understand
1.Client 2.Load balancer 3.Server
Server -Servers are computer programs running to serve the requests of other programs, the clients Thus, the server performs some tasks on behalf of clients. It facilitates the clients to share data, information or any hardware and software resources
The client is the end user who is using …
