- Computer Science Create a simple application for an Admin in a University to manually choose courses for students. The solution would include both Frontend and a minimal Backend. You have to use react node js and mongodb Here, some of the use cases include - Return the list of students, optionally with pagination Display the list of students Upon click on the list item, display the selected courses for that specific student Also, add the option to choose some courses for that student You are free to choose the appropriate UI elements. The result should be runnable ideally via command-line.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. [You are not allowed to use any global variable other than head] If you are using PYTHON, make sure your code has the methods invoked through test statements and proper printing statements according to the tasks. You may create a separate Tester class for this or test the methods within the MyList class. Write a code in pythonWhich of the following is NOT an advantage of linked list over array? Group of answer choices Unlike array, linked list can dynamically grow and shrink during runtime With linked list, we can ensure only the necessary amount of memory space is allocated at any time Accessing a specific element is more efficient with linked list Linked list is better equipped to handle a flexible data structure

Group of answer choices: a. A dynamically resizable array makes insertions at the beginning of an array very efficient. b. Using a doubly linked list is more efficient than an array when accessing the ith element of a structure. c. A dynamically resizable array is another name for a linked list. d. Any type of list tends to be better than an array when there are a set number of maximum items known beforehand. e. If many deletions at any place in the structure were common, a linked list implementation would likely be preferable to an arrayHello, I am having an error and cannot figure out how to solve this question.

You need a data structure that will allow you to store a large set of distinctive objects. The common operations performed on the set of objects are: lookup, insert, and delete. No traversal will be performed on the data set. The client wants the program to be as efficient as possible. Which of the following data structures should you use in your design? Question 25 options: hash table linked list heap binary search treeComputer Science create a program in Java using a singly linked list data structure that allows Sahara Green to keep inventory of all products and where each node in your linked list represents a product sold by Sahara Green. generate a few predefined reports. The system should allow the user (employees) to: 1. Add product details to the system. 2. Search and edit/update the product cost. 3. Search and edit/update the product quantity. 4. Search for a product and display all details for that product. 5. Search and list all products that must be sold within two days (current day) as per the company policy to guarantee freshness. 6.

- Coding language: C++. (Try to avoid linked lists if possible please). Add comments. Thanks. • Each functionality component must be implemented as a separate function, though the function does not need to be declared and defined separately • No global variables are allowed • No separate.hor.hpp are allowed • You may not use any of the hash tables, or hashing functions provided by the STL or Boost library to implement your hash table • Appropriate, informative messages must be provided for prompts and outputs You must implement a hash table using the Double Hashing collision strategy and the mid-square base 10 hashing function with an R of 2. Your collision strategy must be implemented as a separate function, though it may be implemented inside your insert/search/delete functions, and should halt an insert / search/delete functions, and should halt an insert/search/delete after table size number of collisions. Your hash function must be implemented as a separate function. Your hash table…Which of the following statement or statements are true ? Please check all that apply. Both the linkedlist and array size needs to be pre-decided Arrays have better cache locality that can make them better in terms of performance. It's easier to insert and delete elements from array than from the linkedlist Data type of the linked list doesnot need to be same, whereas in array, it must be the same memory can be allocated at runtime both for linkedlist and dynamic array Which of the following statements are true? Check all that applies 5 points Accessing any element of an array has the time complexity of O(n) Searching for an element in array and linkedlist has the same time complexity Inserting or Deleting an element from a stack or queue has the same time complexity Accessing an element from a singly…Python question: This requires knowledge of gensim NLP package.
