A new key is always inserted at the leaf. We start searching a key from the root until we hit a leaf node. Once a leaf node is found, the new node is added as a child of the leaf node. struct insert_into_bst{ void operator()(const Book& book){ /* Otherwise, recur down the tree */ if (item < book->item) node->left = insert(book->left, item); else if (item > book->item) book->right = insert(book->right, item); /* return the (unchanged) node pointer */ return ; } }

Program 3: Binary Search Tree Program Objective 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 all their stamina, they vanish from the…
