Read , Sort , Merge
Using the ListNode structure of Program 17-2, write the following functions:
ListNode *read()
ListNode *sort(ListNode* list1)
ListNode *merge(ListNode* list1, ListNode* list2)
The first function reads a sequence of whitespace-separated positive numbers and forms the numbers read into a linked list of nodes. The input for a sequence of numbers is terminated by - 1. The second function sorts a linked list of nodes and returns a pointer to the head of the sorted lists. The function should sort by rearranging existing nodes, not by making copies of existing nodes. The third function merges two linked lists that are already sorted into a linked list that is also sorted. The merge function should not make copies of nodes: Rather, it must remove nodes from the two lists and form those nodes into a new list.
Test your functions by having the user enter two sequences of numbers, sorting each sequence, and then merging and printing the resulting list.

- #### Part 1 Write a Python function (`binary_search`) that implements the binary search algorithm. This function will take a list argument (`values`), a value to search for (`to_find`), a start index (`start_index`), and an end index (`end_index`). The function will return `True` if `to_find` is present in `values`, and `False` otherwise. Below, you will find some code to test your binary search: ```python values = [2,4,6,8,10,12,14,16,18,20] print(binary_search(values, 14, 0, len(values) - 1)) print(binary_search(values, 7, 0, len(values) - 1)) ``` The output of the test code is below: ``` True False ``` #### Part 2 Modify your `binary_search` function to count the number of comparisons (==, <, <=, >, or >=). The function will now return both the number of comparisons made and the `True` or `False` result. The code below calls your function, and creates a simple ASCII bar chart of the number of comparisons (divided by 10, to account for small differences).

- Write the code to create a linked list using c++ Include the following functionality: Insert at the head or tail of the list. Delete one item (based on an entered value) or all of the list. Print out the linked list. Use the following class and struct to create your linked list: #include <iostream> #include <algorithm> using std::cout; using std::endl; using std::swap; struct Node { int m_data; Node* m_next; }; class LList { public: LList(); LList(int data); LList(const LList& copy); LList(LList&& move) noexcept; ~LList(); int getData(); Node* getNext(); void setData(int data); void insertHead(int data); void insertTail(int data); void deleteNode(int data); void setNext(LList* next); LList& operator = (const LList& copy); LList& operator = (LList&& move) noexcept; void printList(); private: Node* head; };arrow_forwardUsing the ListNode structure introduced in this chapter, write a function void printFirst(ListNode *ptr)that prints the value stored in the first node of a list passed to it as parameter. The function should print an error message and terminate the program if the list passed to it is empty.arrow_forwardWrite the following function that merges two sorted lists into a new sorted list:def merge(list1, list2): Implement the function in a way that takes len(list1) + len(list2) comparisons.
