1. Given the two binary trees below: 4 2 5 6 3 3 4 5 7 (14) (15) (16) 18) 17 (20) Write a method called swapSubtrees, which swaps all of the left and right subtrees in the above binary trees. Add this method to the class Binary Tree and create a program to test this method for these 2 trees. Show the original trees and the resulting trees. Note: To test your algorithm, first create a binary search tree. - Write a method called singleParent, which returns the number of nodes in a binary tree that have only one child for the 2 trees given in the above. Add this method to the class Binary Tree and create a program to test this method. Note: To test your algorithm, first create a binary search tree. 2. Start with an empty heap, and enter ten items with priorities 1 through 10. Draw the resulting heap. - Now remove three entries from the heap that you created in the above exercise. Draw the resulting heap.

Instructions. c++ binary search trees. 1. Implement a function that will build a binary search tree. 2. Using the function above create a binary search tree. 3. Implement a swapSubtrees() function that will take a pointer to a root node and a target value. Function will search for the target value in the tree and swap all left nodes with right nodes for all descendant nodes. 4. Pass the tree created in step 2 to test swapSubtrees() function. 5. You can use the inorder, postorder or preorder traversal implemented in class to display and confirm the logic. (trace it by hand as well) TreeNode{ int val; TreeNode* left = nullptr; TreeNode* right = nullptr; TreeNode(){} TreeNode(int val): val(val){} };
*Please using JAVA only* Objective Program 3: Binary Search Tree Program The primary objective of this program is to learn to implement binary search trees and to combine their functionalities with linked lists. Program Description In a multiplayer game, players' avatars are placed in a large game scene, and each avatar has its information in the game. Write a program to manage players' information in a multiplayer game using a Binary Search (BS) tree for a multiplayer game. A node in the BS tree represents each player. Each player should have an ID number, avatar name, and stamina level. The players will be arranged in the BS tree based on their ID numbers. If there is only one player in the game scene, it is represented by one node (root) in the tree. Once another player enters the game scene, a new node will be created and inserted in the BS tree based on the player ID number. Players during the gameplay will receive hits that reduce their stamina. If the players lose…

Data Structures and algorithms: Topic: Doubly and circular Linked Lists in java: Please solve this on urgent basis: Attach output's picture and explain every statement in commments: Create a doubly Linked list, So far you have come across with numbers that are prime and you have a great knowledge about them using that knowledge help Alice solve the problem of finding all the numbers that are prime and collectively return the sum of those prime numbers stored in doubly linked list. You can use more than 1 function to solve this problem. For example Linked List contains Data: 8,12,3,17,11, Output: 31 Explanation: 3+17+11 = 31
4. A feature of binary search tree is that duplicate values are discarded when insertions are made into the tree. This is referred to as duplicate elimination. Write a program that produces 20 random numbers between 1 and 20. The program should store all nonduplicate values in an array. Use the smallest possible array to accomplish this task.
Assuming the node class has already been created, start your code from the method: def swapReplaceMidOdd(head, element): #write your code here

3. void insert (Node newElement) or def insert(self, newElement) (4) Pre-condition: None. Post-condition: This method inserts newElement at the tail of the list. If an element with the same key as newElement already exists in the list, then it concludes the key already exists and does not insert the key.
