Driver program to perform operations in graph

Driver program to perform operations in graph:-



package com.problems.graph;

public class GraphDriver {

 public static void main(String[] args)
 {
  BFSGraph g=new BFSGraph();
  g.addVertex('A');
  g.addVertex('B');
  g.addVertex('C');
  g.addVertex('D');
  g.addVertex('E');
  g.addVertex('F');
  g.addVertex('G');
  g.addVertex('H');
 
  g.addEdge(0, 1);
  g.addEdge(1, 2);
  g.addEdge(1, 7);
  g.addEdge(2, 3);
  g.addEdge(2, 4);
  g.addEdge(7, 4);
  g.addEdge(4, 5);
  g.addEdge(4, 6);
  g.bfs();
 }
 
}

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



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