NEED THIS PROGRAMS IN C++ AND WITH COMPLETE CODE.

ASAP!

21. Write a function to perform QuickSort algorithm. Make sure to write any other functions (i.e. partition, swap, etc.) needed to execute the quick sort.

          22.   Write a function to implement either the MergeSort or HeapSort sorting algorithm. Just like with the quicksort, make sure you write any other functions needed to execute the sorting algorithm of your choice.

          23.   Write a function that will insert a new key into a binary search tree. Assume that the function takes two parameters: root and newValue, where root is the root of the binary search tree and newValue is the new key to be inserted into the binary tree.

    C++ (b) Consider a binary search tree of positive integers without duplicates. Implement (write out) a program to find the second greatest element in the tree. The Second function is a member function of class BinarySearchTree. The function returns zero if the tree is empty or has only one element, otherwise it returns the value of the second greatest element. Based on the classes provided below, write the implementation of Second in the solution box, including any helper functions (if...
