DO NOT print the dummy head node.

The function will replace all occurrences of old item with new item (if old item exists !!) and it will return the number of replacements done.C++ PROGRAM Consider a single linked list. All parts of question refer to the following declaration. class Node { public: string Value; Node *Next; }; Node *Temp1; Node Temp2; Temp1 = new Node; Use Temp1 to assign the string "hello" to the Node object's Value data-member. Assuming that Temp1 points to a list of Nodes that looks like this: PIC ATTACHED Write code that will insert a new Node containing the value 7 into the list after the Node containing 6 and before the Node containing 12.You don’t need to write code that searches for the values 6 or 12 just use pointer values shown in the picture.
- Programming in C: Challenge 1: Create and Print a Doubly Linked List In class, I briefly mentioned how to create a doubly linked list (a linked list with two directions: forward and backwards). This task challenges you to create a doubly linked list of 5 nodes. If your nodes were called n1, n2, n3, n4 and n5 (which they shouldn’t, please give them original names), your list should be linked as follows: We discussed what "start" and "end" should be. Then, also in main, you will have to print the list forwards by taking advantage of the arrows pointing to the right. You will also have to print it backwards taking advantage of the arrows pointing to the left. Again, everything must be done in main. Hint: look at the way in which I printed the singly linked list in class. In other words, if your nodes had the values: n1=1, n2=2, n3=3, n4=4 and n5=5; your program should print:1 3 5 2 4 (forwards) and 4 2 5 3 1 (backwards). Please give different values to your nodes, they should not have…Exercise, maxCylinderVolume F# system function such as min or methods in the list module such as List.map are not allowed Write a function maxCylinderVolume that takes a list of floating-point tuples that represent dimensions of a cylinder and returns the volume of the cylinder that has the largest volume. Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0. Examples: > maxCylinderVolume [(2.1, 3.4); (4.7, 2.8); (0.9, 6.1); (3.2, 5.4)];;val it : float = 194.3137888> maxCylinderVolume [(0.33, 0.66)];;val it : float = 0.2257988304in c++ A frequency table lists words and the number of times each word appears in a text file.Write a program that creates a frequency table for a file whose name is entered by theuser. You can use a map of string-int pairs. You may want to use the C library functionispunct() (in header file CTYPE.H) to check for punctuation so you can strip it off theend of a word, using the string member function substr(). Also, the tolower() functionmay prove handy for uncapitalizing words.
