Given the definitions of a Node struct and head pointer, write C++ statements to perform the following tasks: a.output the count of all the numbers in the list that are greater than 20 b.output the value of the node preceding the node containing the value 100.c.assuming p is already pointing to a node, insert a node containing 25 after that node.

1 Write a C++ code using a while statement to compute the average of all alternative nodes (1st, 3rd, 5th ...) in the given linked list where the first node is pointed to by first. NOTE: Each node has data member that stores the data and the next member that stores the address of the next node. ( means; there are any number of nodes) Use the following declaration: first Node* next; struct Node { }; int data; double total = double average; Node* temp = first; int count 0; = 0;

] ] get_nhbr In the cell below, you are to write a function called "get_nhbr(Ist, graph)" that takes in two inputs: a list of vertices and a graph. The function is to return a list that contains the neighborhood of the vertices in 'Ist' (remember that this means you are finding the union of the individual vertices' neighborhoods). + Code + Markdown After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (get_nhbr(["A", "D"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]}), get_nhbr(["B", "C", "F"], {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E":["B","C","F"], "F":["E"]})) This should return ["B"] ["A", "D", "E"] Python Python

C++ Programing D.S.Malik 16-13\ This chapter defined and identified various operations on a circular linked list. Use the definitions of the class circularLinkedList and its member functions. (You may assume that the elements of the circular linked list are in ascending order.) In the main.cpp file, write a program to test various operations of the class defined in the step above. Your program should accept a sorted list as input and output the following: The length of the list. The list after deleting a number. A message indicating if a number is contained in the list.
