5 numbers in an empty binary tree
You insert 5 numbers to an empty binary search tree. The numbers output from applying in-order scan algorithm to this tree are:
4 7 8 9 11
and the numbers output from applying level-order scan algorithm to the tree are
7 4 9 8 11
What is(are) leaf…

Trying to use getInorderIterator but its not printing my tree InOrder
I created a binary search tree and I am able to add and remove to it but when i try to use the getInorderIterator method and print the tree it prints "TreePackage.BinaryTree$InorderIterator@2e817b38"
maybe im just calling the method the wrong…

Need help understanding inorder successor in binary search tree
I need help in understanding this interview question:
Q: Find an algorithm to find the next node (e.g., inorder successor) of a given node in a binary search tree where each node has a link to its parent.
Does parent mean the in-order predecessor…

Pre-Order Traversals Of All Possible Binary Trees Given In-Order Traversal
I was looking at questions on binary trees, and I came across the following:
Given the in-order traversal of a binary tree, print the pre-order traversals of all possible binary trees satisfying the given in-order traversal.
For e.g, if the…

Print a binary tree, python, in inorder
Me and my friend are doing some school work with programming in Python 3.1 and are VERY stuck. We're programming a binary tree and it's working fine except when we want to print all the nodes in inorder in a way that would create a sentence (all the…

How to verify a method is called at most n times to work with InOrder of Mockito
I want to verify getCurrentPrice() for at most 15 times. I tried to use atMost() as you can see in my code, but when I ran it, it shows AtMost is not implemented to work with InOrder. How to figure out this problem?

Inorder traversal confusion
Currently, my main code for binary search tree looks like this:
public void add(int value) {
overallRoot = add(overallRoot, value);
}
private IntTreeNode add(IntTreeNode root, int value) {
if(root == null){
root = new…

Time Complexity of printing BST using inorder successor method
I have a method for finding the next inorder successor within a Binary Search Tree (BST). The "inorderSuccessor" method takes any node of the BST as input and output the next inorder successor. The method and tree class are defined as follow:
class…

Binary tree inorder traversal in Python
I don't think I'm traversing it correctly and its returning empty when it needs to return a new list. I've been stuck for a while and still need to do all the other traversals. Will provide unit test for needed output but my unit test might be…

Can this implementation of in-order traversal of a binary tree be improved?
I wrote a straightforward in-order-traversal function (toList1) for a binary tree. However, I worry about its complexity (memory / time). Is there a better way to implement it?
data Tree a = Empty | Node a (Tree a) (Tree a)
toList1 :: (Tree a) ->…

Find a binary tree given only in-order traversal
I'm given an in-order traversal and need to find a binary tree. I referred my sites and most of them said it is not possible. However, i think a non-unique binary tree is possible. Can i find a binary tree using just given in-order traversal? If…
