Need to be done in C++ Please Sorted number list implementation with linked lists Step 1: Inspect the Node.h file Inspect the class declaration for a doubly-linked list node in Node.h. Access Node.h by clicking on the orange arrow next to main.cpp at the top of the coding window. The Node class has three member variables: a double data value, a pointer to the next node, and a pointer to the previous node. Each member variable is protected. So code outside of the class must use the provided getter and setter member functions to get or set a member variable. Node.h is read only, since no changes are required. Step 2: Implement the Insert() member function A class for a sorted, doubly-linked list is declared in SortedNumberList.h. Implement the SortedNumberList class's Insert() member function. The function must create a new node with the parameter value, then insert the node into the proper sorted position in the linked list. Ex: Suppose a SortedNumberList's current list is 23 47.25 86, then Insert(33.5) is called. A new node with data value 33.5 is created and inserted between 23 and 47.25, thus preserving the list's sorted order and yielding: 23 35.5 47.25 86 Step 3: Test in develop mode Code in main() takes a space-separated list of numbers and inserts each into a SortedNumberList. The list is displayed after each insertion. Ex: If input is then output is: Try various program inputs, ensuring that each outputs a sorted list. Step 4: Implement the Remove() member function Implement the SortedNumberList class's Remove() member function. The function takes a parameter for the number to be removed from the list. If the number does not exist in the list, the list is not changed and false is returned. Otherwise, the first instance of the number is removed from the list and true is returned. Uncomment the commented-out part in main() that reads a second input line and removes numbers from the list. Test in develop mode to ensure that insertion and removal both work properly, then submit code for grading. Ex: If input is then output is: Main.cpp #include <iostream> #include <string> #include <vector> #include "Node.h" #include "SortedNumberList.h" using namespace std; void PrintList(SortedNumberList& list); vector<string> SpaceSplit(string source); int main(int argc, char *argv[]) { // Read the line of input numbers string inputLine; getline(cin, inputLine); // Split on space character vector<string> terms = SpaceSplit(inputLine); // Insert each value and show the sorted list's contents after each insertion SortedNumberList list; for (auto term : terms) { double number = stod(term); cout << "List after inserting " << number << ": " << endl; list.Insert(number); PrintList(list); } /* // Read the input line with numbers to remove getline(cin, inputLine); terms = SpaceSplit(inputLine); // Remove each value for (auto term : terms) { double number = stod(term); cout << "List after removing " << number << ": " << endl; list.Remove(number); PrintList(list).

Sorted number list implementation with linked lists
Step 1: Inspect the Node.h file
Inspect the class declaration for a doubly-linked list node in Node.h. Access Node.h by clicking
on the orange arrow next to main.cpp at the top of the coding window. The Node class has three
member variables:
a double data value,
a pointer to the next node, and
a pointer to the previous node.
Each member variable is protected. So code outside of the class must use the provided getter and
setter member functions to get or set a member variable.
Node.h is read only, since no changes are required.
Step 2: Implement the Insert() member function
A class for a sorted, doubly-linked list is declared in SortedNumberList.h. Implement the
SortedNumberList class's Insert() member function. The function must create a new node with
the parameter value, then insert the node into the proper sorted position in the linked list. Ex:
Suppose a SortedNumberList's current list is 23 47.25 86, then Insert(33.5) is called. A new node
with data value 33.5 is created and inserted between 23 and 47.25, thus preserving the list's
sorted order and yielding: 23 35.5 47.25 86
Step 3: Test in develop mode
Code in main() takes a space-separated list of numbers and inserts each into a SortedNumberList.
The list is displayed after each insertion. Ex: If input is
then output is:
Try various program inputs, ensuring that each outputs a sorted list.
Step 4: Implement the Remove() member function
Implement the SortedNumberList class's Remove() member function. The function takes a
parameter for the number to be removed from the list. If the number does not exist in the list, the
list is not changed and false is returned. Otherwise, the first instance of the number is removed
from the list and true is returned.

2. Uncomment the commented-out part in main() that reads a second input line and removes
numbers from the list. Test in develop mode to ensure that insertion and removal both work
properly, then submit code for grading. Ex: If input is
then output is:
Main.cpp
#include <iostream>
#include <string>
#include <vector>
#include "Node.h"
#include "SortedNumberList.h"
using namespace std;
void PrintList(SortedNumberList& list);
vector<string> SpaceSplit(string source);
int main(int argc, char *argv[]) {
// Read the line of input numbers
string inputLine;
getline(cin, inputLine);
// Split on space character
vector<string> terms = SpaceSplit(inputLine);
// Insert each value and show the sorted list's contents after each insertion
SortedNumberList list;
for (auto term : terms) {
double number = stod(term);
cout << "List after inserting " << number << ": " << endl;
list.Insert(number);
PrintList(list);
}
/*
// Read the input line with numbers to remove
getline(cin, inputLine);
terms = SpaceSplit(inputLine);
// Remove each value
for (auto term : terms) {
double number = stod(term);
cout << "List after removing " << number << ": " << endl;
list.Remove(number);
PrintList(list);

3. }
*/
return 0;
}
// Prints the SortedNumberList's contents, in order from head to tail
void PrintList(SortedNumberList& list) {
Node* node = list.head;
while (node) {
cout << node->GetData() << " ";
node = node->GetNext();
}
cout << endl;
}
// Splits a string at each space character, adding each substring to the vector
vector<string> SpaceSplit(string source) {
vector<string> result;
size_t start = 0;
for (size_t i = 0; i < source.length(); i++) {
if (' ' == source[i]) {
result.push_back(source.substr(start, i - start));
start = i + 1;
}
}
result.push_back(source.substr(start));
return result;
