Chapter 13.1, Problem 8STE

Suppose your program contains type definitions and pointer variable declarations as in Self-Test Exercise 7. Suppose further that p2 points to a node of type Node that is on a linked list and is not the last node on the list. Write code that will delete the node after the node pointed to by P2. After this code is executed, the linked list should be the same, except that there will be one less node on the linked list. (Hint: You might want to declare another pointer variable to use.)

I want to count the number of nodes in a linked list. Each node of the list is a class called node. Each node of the list contains a pointer to the next node of the list called next. The variable start has the address of the first node in the list. If the list is empty start is set to null. The pointer t the end of the list is set to null. Which of the following code segments produces an accurate count of the nodes in the list. The answer is returned as an integer. O int count = 1; node ptr start; while(ptr != null){ ptr=ptr.next; count++; } return (count - 1); Oint count = 1; node ptr start; while(ptr.next != null){ ptr-ptr.next; count++; } return count; O int count = 0; node ptr start; while(ptr != null){ ptr-ptr.next; count++; } return count; O int count = 0; node ptr = null; while(ptr != null){ ptr-ptr.next; count++; } return count;
The following question requires to be done in Python. Thanks in advance
Please write a full C++ code The function insert of the class orderedLinkedList does not check if the item to be inserted is already in the list; that is, it does not check for duplicates. Rewrite the definition of the function insert so that before inserting the item, it checks whether the item to be inserted is already in the list. If the item to be inserted is already in the list, the function outputs an appropriate error message. Also, write a program to test your function Also please allow the code to be copied. Don't just provide a screenshot
