this code is a binary search tree I'm doing for my school assignment. #include "binary_tree.h" #include <stdio.h> #include <stdlib.h> #include <string.h> #define MAXLEN 10 Node* create_tree() { return NULL; } void insert_tree(N
I was trying to understand BST from this link BinarySearchTree. But i have got confused in the else part /* Functions to delete data */ public void delete(int k) { if (isEmpty()) System.out.println("Tree Empty"); else if (search(k) == false) Sys
Is it possible to insert a sequence of non-unique elements into an AVL Tree? For example, what is the AVL Tree result of inserting 3, 3, and 3 into an initially empty AVL Tree? is it: 3 / \ 3 3
This is from Heap lecture slide 8. Add, peek, and remove make sense to me as to why those operations are O(log n)- traversing through BST cuts tree in half after each move. Can anyone explain the intuition behind the last sentence though, that "The t
I need to help about my final exam questions.They just true or false.But if you choose false explain why.Btw ı dont wanna sound a lazy student.I will write my answer then check up with your answers. 1.T-F The height of any binary search tree with n n
I have a class Tree that I'd like to augment into more specialized data structures, such as Order_tree and Interval_tree. These augmentations require additions to the Node, such as size information, and minor alterations to some algorithms. I'd like
I've made a tree with: mytree[3]="red" mytree[4]="blue" mytree[6]="yellow" mytree[2]="at". But if I try to delete the root node, 3, with mytree.delete(3), I get an AttributeError. 'TreeNode' object has no attribute 'findSuccessor'. Any idea why this
I have a lab assignment that I have been working on for the last couple of weeks and I am stuck and desperately need help as this will be about 50% of the final project. The assignment is to create a Binary Search Tree in C++. We have to read in the
Assume I have unique keys from 1 to n to insert in a BST. I understand that if keys are inserted randomly, they will have roughly a 50% chance of being smaller, or greater than the root, and in such a scenario, my tree will have an approximately mini
I'm learning about BST's and I ran into this error. I originally had the Node as a struct and it worked fine when I directly accessed the left/right members. I'm trying to make Node a class and use accessor functions instead. Edit: I'm using an inter
I attempted to build a binary search tree builder method. However I think I am missing something. I tested my method with inOrderPrint method and a treeHeigh method. How my method works is that a root node is the first parameter. The second parameter
One of the biggest advantages of using heaps for priority queues (as opposed to, say, red-black trees) seems to be space-efficiency: unlike balanced BSTs, heaps only require O(1) auxiliary storage. i.e, the ordering of the elements alone is sufficien
Problem Description: (language is java) Given an input array representing a preorder traversal of a binary search tree, output a postorder traversal of the BST. Catch : No construction of BST nodes. No recursions. O(n) running time. I have tried figu
I have an assignment in class where we are implementing a BST with lazy deletion. When a node is removed it is just flagged as deleted and not actually removed from the tree. We have to create a method for the case when we want to actually hard delet
I want to maintain two related binary search trees the nodes of which hold two items of data - a page number and a time of creation/reference (the details are not that important - essentially it is two 64 bit numbers). The first tree is ordered by pa
I want to be able to say trim<' ', '\t', '\n'>(str), have it use is_ws<' ', '\t', '\n'>(ch) underneath as a predicate. And I want the predicate to do O(log(N)) comparisons for each ch. Not compiling(ambiguous signature) O(N) fragment to d
I have an exam tomorrow morning and I have some questions about some code on practice exams. I am given code that I need to identify errors for and describe what happens at runtime. Binary search tree algorithm The deletion cases for no child, left c
I adapted my code from from this book: Data Structures and Algorithms by Mark Allen Weiss, 3rd edition. Every time I run it, it crashes. By request I'll add the entire Binary Tree code(its long). Whenever I try to run it in debug mode, I end up cycli
I'm getting an exception when I run my program. It compiles ok and it was working earlier so I'm not sure what's wrong. The error: http://gyazo.com/091235db6cc37154e8f7304e4c1482a8 It's supposed to print out a sequence given in a sideways tree. impor
Is this method wrong for finding out if the tree is a BST or not? The left subtree of a node contains only nodes with keys less than the node’s key.The right subtree of a node contains only nodes with keys greater than the node’s key.And Both the lef
