Write a C code for this. Find the  sum of all left child values for the binary tree.     (Note: Use array to implement the binary tree and  ‘0’ represents the null value if there is no child)    Example:        ​​Input :    Number of nodes in the tree including empty child : 13    Array representation of the tree is :  5,4,8,11,0,13,4,7,2,0,0,0,1    Output:    sum of all left child values = 4+11+13+7 =35​

Code in Python:

24. Add the following new method in the BST class. /** Returns the number of nodes in this binary tree */ public int getNumberofNodes () Requirements: a. Don't use return size; b.write a recursive method that returns the number of nodes starting from www the root.

Quick Sort We choose an element from the list, called the pivot. We'll use it to divide the list into two sub-lists. We reorder all the elements around the pivot The ones with smaller value are placed before it All the elements greater than the pivot after it. After this step, the pivot is in its final position. This is the important partition step. We apply the above steps recursively to both sub-lists on the left and right of the pivot.   Quick Sort (Example) Consider the following array Arr[] = {5, 9, 4, 6, 5, 3} Let's suppose we pick 5 as the pivot for simplicity We'll first put all elements less than 5 in the first position of the array: {3, 4, 5, 6, 5, 9} We'll then repeat it for the left sub-array {3,4}, taking 3 as the pivot There are no elements less than 3 We apply quicksort on the sub-array in the right of the pivot, i.e. {4} This sub-array consists of only one sorted element We continue with the right part of the original array, {6, 5, 9} until we get the final ordered…

Can you help me with a C++ programming task I am trying to complete for myself please: Write a program (in main.cpp) that: Prompts the user for a filename containing node data. Outputs the minimal spanning tree for a given graph. You will need to implement the createSpanningGraph method in minimalSpanTreeType.h to create the graph and the weight matrix. There are a few tabs: main.cpp, graphType.h, linkedList.h, linkedQueue.h, queueADT.h, minimalSpanTreeType.h, and then two data files labeled: CH20_Ex21Data.txt, CH20Ex4Data.txt

C programming help   get numbers from user using a struct that points(pointer) into a binary search tree and another pointer into a array to use merge sort on the array then prints out all the numbers and at what hight they are in the binary tree and also prints out the sorted array

8-Write a procedure that takes a tree (represented as a list) and returns a list whose elements are all the leaves of the tree arranged in right to left order or left to right. For example, ( leaves '((1 2) ((3 4) 5 )) returns (1 2 3 4 5) or (5 4 3 2 1). Then, Manually trace your procedure with the provided example.
