Consider the following linked list of the form. This list already exists, so you do not need to write the code to create the list below: struct nodeType { int infoData; nodeType * next; }; nodeType *first; … and containing the values: first (( See image for values )) Use this linked list to perform the following actions. Declare any additional pointers, etc., if needed, to complete the code. You do not need to write any includes or using statements—just program segments. Write a code segment that creates a new node with infoData = 13 and inserts the node after the node with the value 12.
java Please provide Comment and test cases Create a Linked List data structure by writing your own Linked List class which contains a node class. The node class will house the data (integer in this case) and a pointer to the next node element. Populate your linked list with the following integers and print it . 50, 11, 33, 21, 40, 71 No you do not need to print the commas ;) Delete N-th node from the end of the linked list and print the linked list after deletion. Here N = 2 Below is the expected output after deleting the second last element. 50, 11, 33, 21, 71 ATTN : Note : Here we do not know the length of the list. Complete the above deletion operation without calculating the length of the list. Your solution should only make a single pass through the linked list, adhering to O(n) time complexity overall and O(1) space complexity. Hint : Maintain two pointers : a ’Fast’ Pointer and a ’Slow’ pointer. Initialize both pointers to a dummy node which points to the head of the list.…
Don't copy from anywhere... please fast... typed answer Assignment: Linked List of Students You have been tasked with implementing a program in Java that uses a linked list to store and manage a list of students in a class. Each student should have a name and a grade. Your program should include the following classes: Student: Represents a student in the class. Each student should have a name and a grade. Node: Represents a node in the linked list. Each node should store a reference to a student and a reference to the next node in the list. LinkedList: Represents the linked list itself. Each linked list should have a reference to the first node in the list. Your task is to implement these classes using a linked list and demonstrate their functionality by creating a console-based interface for users to interact with the system. Your program should allow users to: Add a new student to the class at the end of the list. View information about a student, including their name and grade.…
i) Create a Node class which will hold two fields i.e an integer element and a reference to the next Node. ii) Create a Linked list Abstract Data Type (ADT)named MyList.The elements in the list are Nodes consisting of an integer type key (all keys are unique) and a reference to the next node. Use Python Language.

E.g., if the input is "Quiz 25", the function returns a list: ["Quiz", 25.0] If splitting the `info` string does not result in a two-element list, then return -2.

Using Java programming language create a linked list named Cars with four elements: "SUV cars", "Pickup cars", "Sport cars", and "Sedan cars". Apply the following activities on the code you’ve created and provide screen shot of each result: Add a new element “Classic car” at the beginning of the linked list using iterator. Add a new element “Economic cars" after the element "Sedan Cars" using iterator. Print the LinkedList backward from the last element to the first element using hasPrevious()

1-Let the list have a head and a tail. That is, a pointer (have a marker) to both the beginning (first Node) of the list and the last Node. What process does Tail facilitate? 2-insert(int index, int element): adds this element to the index position. For example, if index is 4, it adds this element between index 3 and 4 in the list. The size of the list has increased by one. 3-append(int elem): Adds the element to the end of the list. The size of the list has increased by one. 4-get(int index): Returns the element at the index position of the list, no change in the list. 5-remove(int index): Returns the element at the index position of the list. This element is removed from the list and the list size is reduced by one. 6-findMin(): returns the index of the smallest number in the list. 7-findMax(): returns the index of the largest number in the list. 8-search(int elem): searches elem in the list. It returns -1 when you can't find elem's index when you find it. 9-ToArray(): Return an…
