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 ); Sy
