Shared pointers: A “shared_ptr” is a smart pointer which maintains shared ownership of an object using pointer. Shared pointers are used in managing the ownership of the dynamically allocated object. Shared pointers are used by more than one owner available for the objects that are allocated dynamically. Example: The following code illustrates the use and creation of shared pointer: //creating a shared pointer of integer data type shared_ptr<int> sDPtr1 (new int); //creating an array of shared pointer shared_ptr<int[]> sDPtr2 (new int[5]); Explanation: In the above code snippet, a smart pointer of integer data type is assigned directly.

Program Plan Intro

Shared pointers:

A “shared_ptr” is a smart pointer which maintains shared ownership of an object using pointer.

Shared pointers are used in managing the ownership of the dynamically allocated object.

Shared pointers are used by more than one owner available for the objects that are allocated dynamically.

Example:

The following code illustrates the use and creation of shared pointer:

//creating a shared pointer of integer data type

shared_ptr<int> sDPtr1 (new int);

//creating an array of shared pointer

shared_ptr<int[]> sDPtr2 (new int[5]);

Explanation:

In the above code snippet, a smart pointer of integer data type is assigned directly.

Objective you will: 1. Implement a Binary Search Tree (BST) from scratch, including the Big Five (Rule of Five) 2. Implement the TreeSort algorithm using a in-order traversal to store sorted elements in a vector. 3. Compare the performance of TreeSort with C++'s std::sort on large datasets. Part 1: Understanding TreeSort How TreeSort Works TreeSort is a comparison-based sorting algorithm that leverages a Binary Search Tree (BST): 1. Insert all elements into a BST (logically sorting them). 2. Traverse the BST in-order to extract elements in sorted order. 3. Store the sorted elements in a vector.
