What considerations do you have to keep in mind when choosing between physical, hybrid, or virtual server and what are the reasons to choose a virtual installation over the other options?
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.  Time Complexity Operation                                Average Case     Worst Case (Unbalanced Tree)Insertion                                     0(1log n)                0 (n)Traversal (Pre-order)                  0(n)                       0 (n)Overall Complexity                  0(n log n)                 0(n^2) (degenerated tree) Note: To improve performance, you could use a…
