Add (to the ArrayList) all the marks information about a coursework or research student byreading it from another text file and determine the student’s overall mark and grade.You will need to consider how to deal with the different assessment components for thecoursework and research students. You may use two different text files, one for courseworkstudents and another for research students. The program should read the correct text file forthis purpose.3. Given student number (ID), remove the specified student and relevant information from theArrayList. It is always good to ask the user to confirm again before removing the record. Forconfirmation, output the student number (ID) and the name to the user.4.

- (Tic-Tac-Toe) Write a program that allows two players to play the tic-tac-toe game. Your program must contain the class ticTacToe to implement a ticTacToe object. Include a 3-by-3 two-dimensional array, as a private member variable, to create the board. If needed, include additional member variables. Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move. Add additional operations as needed.arrow_forward- (Minimum and Maximum) We often want to find the minimum and maximum values in a vector as well as the indices at which these values occur. For this problem do not use the built in min or max function (or any other function which trivializes the problem). min_max Function: Input variables: • a vector representing the list of numbers; you may assume each value is unique Output variables: • a scalar representing the minimum value • a scalar representing the index where minimum value is located in the list • a scalar representing the maximum value • a scalar representing the index where maximum value is located in the list A possible sample case is: » [min_val, min_i, max_val, max_i] = min_max(1:5) min_val = 1 min_i max_val = max_i = 1 5 » [min_val, min_i, max_val, max_i] = min_max([2, 3, 7, 1, 4]) min_val = 1 min_i 4 max_val = max_i = 3 7 » [min_val, min_i, max_val, max_i] = LXX_QYY([1, 2, 3, 4, -1, 0]) min_val = -1 min_i max_val = %3D 4 max_i = 4arrow_forwardAnswer in C++ code please! (Duplicate Elimination with vector) Use a vector to solve the following problem. Read in 20 numbers, each of which is between 10 and 100, inclusive. As each number is read, validate it and store it in the vector only if it isn't a duplicate of a number already read. After reading all the values, display only the unique values that the user entered. Begin with an empty vector and use its push_back function to add each unique value to the vector.arrow_forward
- 2, Towers of Hanoi Problem. (10 points) The Towers of Hanoi is a famous problem for studying recursion in computer science and searching in artificial intelligence. We start with N discs of varying sizes on a peg (stacked in order according to size), and two empty pegs. We are allowed to move a disc from one peg to another, but we are never allowed to move a larger disc on top of a smaller disc. The goal is to move all the discs to the rightmost peg (see figure). To solve the problem by using search methods, we need first formulate the problem. Supposing there are K pegs and N disk. Answer the following questions. (1) Determine a state representation for this problem. (4points) (2) What is the size of the state space? (3 points) (3) Supposing K=3, N=4, what is the start state by using your proposed state representation method and what is the goal state?

Sort them in ascending order using the bubble sort technique. Print both the given array and the sorted array with suitable headings.Strictly adhere to the Object-Oriented specifications given in the problem statement. All class names, member variable names, and function names should be the same as specified in the problem statement.Define the sort method in the Sort class. Input Format:The first input consists of an integer which corresponds to the number of elements present in the single dimension array. The next 'n' inputs are the elements in the array. Output Format:The first line output consists of array elements before sorting and the next line of the output consists of array elements after sorting.Refer to sample input and output for formatting specifications.[All text in bold corresponds to input and the rest corresponds to output]…arrow_forwardMatch (std::array member function on left with the correct description on right.
