How to design a Node in Tree?

How to design a Node in Tree?

There are three main components of a tree in a node.

 1) Integer holding data.
2) Left pointer holding node in a left subtree.
3) Right pointer holding node in a right subtree.

The following design is having data of int type and left,right pointers of a node to the subtrees.


package com.BST;

public class Node {

 int data;
 Node left;
 Node right;
 /**
  * @return the data
  */
 public Node(int data)
 {
  this.left=null;
  this.right=null;
  this.data=data;
 }
 
 public int getData() {
  return data;
 }
 /**
  * @param data the data to set
  */
 public void setData(int data) {
  this.data = data;
 }
 /**
  * @return the left
  */
 public Node getLeft() {
  return left;
 }
 /**
  * @param left the left to set
  */
 public void setLeft(Node left) {
  this.left = left;
 }
 /**
  * @return the right
  */
 public Node getRight() {
  return right;
 }
 /**
  * @param right the right to set
  */
 public void setRight(Node right) {
  this.right = right;
 }
 /* (non-Javadoc)
  * @see java.lang.Object#toString()
  */
 @Override
 public String toString() {
  return "Node [data=" + data + ", left=" + left + ", right=" + right
    + "]";
 }

Basics of System Design

This article is first one from the series of articles dedicated to system design interviews. Here i am going to present the base scenario to consider before starting to solve system design problems. Questions to ask? 1) what is the number of requests a website will recieve in a day/month/second? 2) what is the amount of memory a website will deal in a day/month/second? 3) what is the number of servers that can accomodate these requests? To answer this , first we need to remember the below numbers:- 1 million = 10 lakh = 1000000 = 10^6 1 billion = 1000 million = 10^9 1 KB = 1024 B = 10^3 1 MB= 10^6 = 1024 KB 1 GB= 10^9 = 1024 MB 1 TB = 10^12 = 1024 GB Memory we need to see in Bytes Requests we need to see in numbers example :- suppose a website recieves 100M requests every month then:- requests per day = request per month /24 = 416700 requests requests per second = requests per day / (24*360...
