find the inorder traversal of the tree and print them all by negating every alternate number

it helps some times All you might have to do , add a additional argument to keep track of alternate sign, something like following :
Node * func(struct Node * root, int& signV ){
    func(root->lChild, signV);
    cout<<root->nodeValue * signV <<" "; signV *= -1 ; // Change sign here
    func(root->rChild, signV);
  return NULL;

How to print tree in an inorder traversal (java)?

Tag : java , By : acolomba

I hope this helps you . I am trying to print my AVLtree as following, , Here's the code:
void inOrder(AVLNode node, int depth, StringBuilder sb)
  if(node == null) return;

  inOrder(node.left, depth+1, sb);

  for(int a=0;a<depth;a++) sb.append(".");
  sb.append(node.data + "\n");

  inOrder(node.right, depth+1, sb);


Find the inorder traversal from its preorder traversal sequence in binary tree

this will help I don't think you can find out the inorder traversal based on just the preorder traversal for a binary tree. As you said for binary search tree, sorting will give you the inorder traversal.

To fix the issue you can do I am trying to print my AVL tree in the following way: , As Rohit Jain commented, just add them in the printTree method:
private void printTree(Node t){
    if(t != null){
        System.out.print(t.element + " ")

Binary tree - find position in inorder traversal

wish help you to fix your issue You can also use a counter in the recursive approach. However, you can't simply pass an int counter argument - you need all calls to see the "same" counter, so you will have to wrap it in a class (or, as in this case, an inner class):
public static class Counter {
   private int value;
   public Counter(int initialValue) { value = initialValue; }
   public boolean decrement() { value--; return value == 0; }
   public boolean expired() { return value <= 0; }

public Node inOrderTraverseTree(Node root, Counter counter){
   if  (root != null && ! counter.expired()) {
       Node left = inOrderTraverseTree(root.leftChild, counter);
       if (left != null) {
            return left;
       } else if (counter.decrement()) {
            return root;
       } else {
            return inOrderTraverseTree(root.rightChild, counter); 
   } else {
       return null;
Node the9th = inOrderTraverseTree(root, new Counter(9));

Binary Search Tree in java, Inorder traversal is only recognizing a single number in the tree

I wish this helpful for you In your inorder method, you are always printing the root node, instead of the node you are currently at.
Instead of:
System.out.println(root.data + " ");
System.out.println(subtree.data + " ");
