C++ You are given the root node of a binary search tree (BST) and a value to insert into the tree. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Example 1: diagram for example 1 attached Input: root = [4,2,7,1,3], val = 5 Output: [4,2,7,1,3,5] Explanation: Another accepted tree is: Example 2: Input: root = [40,20,60,10,30,50,70], val = 25 Output: [40,20,60,10,30,50,70,null,null,25] Example 3: Input: root = [4,2,7,1,3,null,null,null,null,null,null], val = 5 Output: [4,2,7,1,3,5] Constraints: The number of nodes in the tree will be in the range [0, 104]. -108 <= Node.val <= 108 All the values Node.val are unique. -108 <= val <= 108 It's guaranteed that val does not exist in the original BST.
All of the following are true EXCEPT: An empty tree is defined to have a height of 1. The depth of a node p is the number of ancestors of p, other than p itself. The height of a tree to be equal to the maximum of the depths of its nodes (or zero, if the tree is empty). The height of a node p in a tree T: • If p is a leaf, then the height of p is 0. • Otherwise, the height of p is one more than the maximum of the heights of p's children.
java binary tree: Given the following binary search tree, what would be the sequence of nodes, if traversed using inorder traversal after deleting 8.
Theoretical computer science Hello i need help with this task, 2.Part: Let L1, L2 and L3 be the following languages above the alphabet Σ= {a,b}: L1 = {s1 • aa • s2 | s1, s2 ∈ Σ* }, L2 = {ambn | m, n ∈ IN and m < n}, L3 = {s ∈ Σ* | s does not contain the substring aa}. Subtask (a): Its given the following strings: u1 = ∈, u2 = ab, u3 = aab and u4 = bb. (i) For each of these character strings ui, give the suffix set assigned to itSL1 (ui) on.(ii) For each of these character strings ui, give the suffix set assigned to itSL2 (ui) on.(iii) For each of these character strings ui, give the suffix set assigned to itSL3 (ui) on. Subtask (b): Answer the following questions and give reasons for each of them detailed.(i) Which Nerode index does the language L1 have?(ii) Which Nerode index does the language L2 have?(iii) What is the Nerode index of language L3?
Implement the pre-order tree traversal algorithm in C++. This program should use the following binary tree (see image) and display the pre-order tree traversal of the nodes’ values. Feel free to write this iteratively or recursively. Also, explain how it works and how a new tree could be provided to the code. PS: make sure that the logic of the program is correct, meaning that it can work well with different binary trees. I would like to change the tree input to the pre-order traversal function. The program should work errorless and display the result correctly. No need to code it to read the user input, however, provide instructions on how a new tree can be defined in this program to check if the program works fine with different trees.
How to announce a Linked List Node with three characters in C language, same as the example shown in teaching materials For example is the following figure. EAT O a. struct Node { char *EAT[3]; struct Node next; } Node; O b. struct { Char Three; Link *Next; }; O c. typedef Linked Node { Character EAT; Arrow Link; O d. struct Node { char Three; Arrow Link; }; O e. typedef structure Node { char Name[3]; structure Node *Next; }; O f. structure List Node { Three Character; Link; } O g. typedef struct Node { char name[3]; struct Node *next; } node_C; Oh. typedef struct Node { char EAT; struct *Next; };
Rewrite the definition of the function searchNode of the class B-tree provided (bTree.h) by using a binary search. Write a C++ code to ask the user to enter a list of positive integers ending with -999, build a b- tree of order 5 using the positive integers, and display the tree contents. Also, ask the user to enter a number to search and display if the number is found in the tree. bTree.h
Construct a Binary Search Tree (BST) using the data provided in shaded row and name it “BST-1”. 50 45 65 60 75 90 15 35 70 45 55 40 20 80 95 85 25 50 74 5 Provide answers to the following considering your constructed BST-1: Write a C++ code for the in-order traversal of BST-1. Also, dry run your code on it and elaborate its each step. Compute the total number of used and unused (null) references defined in BST-1. And construct an equivalent two-way in-order threaded BST-1 that has minimum number of null references.
Define a function prefiaSum which takes a list of numbers as its argument and returns a list of sums of all prefixes of the list. For example: • prefixSum [1..10] => [1,3,6,10,15,21,28,36,45,55] prefixSum [2, 5]=> [2,7]
