- Assignment A scientist has developed a mathematical model for a physical process, and he wants to check how good is model is. To evaluate the correctness of his model, he wants to test the results of his model under certain parameters and compare them with experimental results. Write a program that first reads the number of tests (testCount) as an int followed by the results of each test according to the model as a double array (testModel) and finally the results of each test according to experiments as a double array (testExperiment). Then, the program should calculate the error of the model by evaluating the average of the absolute values (i.e., mutlak değer) of the differences between the model result and experimental result (see formula below) using a function. ItestModel,- textExperiment, testCount NOTE: Individual absolute value of the difference between the model value and the experiment value calculations MUST be done in the function. Every other functionality MUST be done in…For the array ADT, the operations associated with the type array are: insert a value in the array, delete a value from the array, and test whether a value is in the array or not. 1.true 2.falseWrite the code of dynamic array with the name of ‘A’ and you will get the size of array from user and also get the values of array from the user and display that values on screen.

- JAVA Your teacher has created two arrays, each holding the results of tests, say Test 1 and Test 2. You need to create a new array which holds the averages of these two tests. You may assume that the first element of the first test array refers to the student who also has the grade in the first element of the second test, and the last element in each array are the grades the last student earned for each test. All students received grades for both tests, meaning both test arrays are of the same length. Complete the method, named makeAverage, in the class named Grades.java. There are two parameters to this method: the first is the integer array representing the grades of the first test, and the second is the array containing the grades of the second test. The new average array should be returned by the method. The grades should be treated as double variables. For example, consider the test grades for the five students in the following arrays: [ 87 ] [ 91 ] [ 76 ] [ 76 ] [ 94 ]…In statistics the mode of a set of values is the value that occurs most often. Write a program that determines how many pieces of pie most people eat in a year. Set up an integer array that can hold responses from 30 people. For each person, enter the number of pieces they say they eat in a year. Then write a function that finds the mode of these 30 values. This will be the number of pie slices eaten by the most people. The function that finds and returns the mode should accept two arguments, an array of integers, and a value indicating how many elements are in the array.Problem: We need a program that takes 8 products and makes calculations and informs the user. Products have name, type and cost. Write the program that takes name,type and cost information from the user and saves the product objects to an array and calculates the total cost, the one with the most cost and the one with the least cost. For example: Banana Fruit 10 Apple Fruit Trousers Textile 50 T-Shirt Textile 30 Pencil Office 15 Office Раper Strawberry Computer 10 Fruit 20 Electronics 6000 Total Cost: 6140 TL Most Expensive: Computer Least Expensive: Apple
- Implement this program to understand use of Arrays in real world examples. A small airline has just purchased a computer for its new automated reservations system. You have been asked to develop the new system. You are to write an application to assign seats on each flight of the airline’s only plane (capacity: 10 seats). Your application should display the following alternatives: Please type 1 for First Class and Please type 2 for Economy. If the user types 1, your application should assign a seat in the first-class section (seats 1–5). If the user types 2, your application should assign a seat in the economy section (seats 6–10). Your application should then display a boarding pass indicating the person’s seat number and whether it is in the first-class or economy section of the plane. Use a one-dimensional array of primitive type boolean to represent the seating chart of the plane. Initialize all the elements of the array to false to indicate that all the…Write a class with name Arrays . This class has an array which should be initialized by user.Write a method Sum that should sum even numbers in array and return sum. write a function with name numFind in this class with working logic as to find the mid number of an array. After finding this number calculate its factorial.Write function that should display sum and factorial.Don’t use divide operatorA scientist has developed a mathematical model for a physical process, and he wants to check how good is model is. To evaluate the correctness of his model, he wants to test the results of his model under certain parameters and compare them with experimental results. Write a program that first reads the number of tests (testCount) as an int followed by the results of each test according to the model as a double array (test Model) and finally the results of each test according to experiments as a double array (testExperiment). Then, the program should calculate the error of the model by evaluating the average of the squares of the differences between the model result and experimental result (see formula below) using a function. Error Input 1 testCount NOTE: Individual square of the difference between the model value and the experiment value calculations MUST be done in the function. Every other functionality MUST be done in the main function. NOTE: To calculate square of a number you…
- in C++ : You are given an array of integers representing asteroids in a row.For each asteroid in the array/row, the absolute value represents its size, and the sign represents its direction (positivemeaning right, negative meaning left). Each asteroid moves at the same speed.Find out the state of the asteroids after all collisions. If two asteroids meet, the smaller one will explode. If both are thesame size, both will explode. Two asteroids moving in the same direction will never meet. Example 1:Input: asteroids = [5,10,-5]Output: [5,10]Explanation: The 10 and -5 collide resulting in 10. The 5 and 10 never collide. Example 2:Input: asteroids = [8,-8]Output: []Explanation: The 8 and -8 collide exploding each other.Write pseudo code for given statemente. The amount variable is set to 0, and then each is called on the array. Each of the values in the array is passed to the block. Each time the block is called, amount is updated:What transpires when a parameter for an array is sent in with either the ref or out keyword, and the results are observed?
