Task 3: Statistics using arrays: by java programming With the spread of COVID 19, the HR department in a company has decided to conduct some statistics among the employees in order to determine the number of infections according to some conditions. For each employee, they have to record the code, name, age, whether he/she was infected or no and the remaining days of leaves for him/her. You are requested to write the program that maintains the lists of details for the employees as mentioned above using the concept of arrays. The program repeats the display of a menu of services until the user decides to exit. 1. Start by initializing the employee details by reading them from the keyboard. 2. Repeat the display of a menu of 4 services, perform the required task according to the user’s choice and asks the user whether he/she wants to repeat or no. You need to choose one service from each category (‘A’,’B’,’C’,’D’) a. A. Display the total number of employees that were infected b. B.…

DESIGN YOUR OWN SETTING Task 5: Devise your own setting for storing and searching the data in an array of non-negative integers redundantly. You may just describe the setting without having to give an explicit algorithm to explain the process by which data is stored. You should explain how hardware failures can be detected in your method. Once you have described the setting, complete the following: Write a pseudocode function to describe an algorithm where the stored data can be searched for a value key: if the data is found, its location in the original array should be returned; -1 should be returned if the data is not found; -2 should be returned if there is a data storage error Include a short commentary explaining why your pseudocode works Describe the worst-case and best-case inputs to your search algorithm Derive the worst-case and best-case running times for the search algorithm Derive the Theta notation for the worst-case and best-case running times Maximum word…

C++ Progrmaing Instructions Redo Programming Exercise 6 of Chapter 8 using dynamic arrays. The instructions have been posted for your convenience. The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form: TFFTFFTTTTFFTFTFTFTT Every other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry: ABC54301 TFTFTFTT TFTFTFFTTFT indicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9 (note the empty space). The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID,…

Programming Language: C++ Please output it in the console not a text file. For this exerc ise, you will define a struct. It will contain a first name, last name, ID, and GPA. You will ask the user how many students to enter, create a dynamic array of that size to get data from the user. The array data will initially be inserted into the array in ID order. Then you will display the array in a table, sort it by last name with std::sort, redisplay it, and then search for five students (using last name and a binary search) and for any names found display the first name, last name, and GPA, The struct will be named Student and include strings for firstName, lastName, ID, and a float for the GPA. The ID will be in the format 00xxxxxx where the x's are replaced by digits and in the range between 111111 and 999999. The GPA will be a floating-point number in the range 2.0 to 4.2 and will be displayed to 2 digits after the decimal point.

PYTHON  In order to parse data to start a simulation, users must enter data correctly. Suppose that the simulation requires 2 information from the user, which is called 'soil_key' and 'soil_data.' The user will enter 'soil_key' first, following with 'soil_data.'  We need to check if the user enters the 'soil_data' data correctly.  All elements in soil data ('soil_data') must be characters defined in the soil keys ('soil_key'). Both soil_key and soil_data are lists. Consider an example: INPUT: soil_key = ['C', 'Clay', ' B', 'Bedrock', ' V', 'Void']  soil_data1 = [ ['V', 'C', 'V'], ['C', 'V', ' '], ['B', 'M', 'B'] ]   soil_data2 = [ ['B', 'C', 'V'], ['C', 'V', ' B'], ['B', 'C', 'B'] ]   OUTPUT: soil_data1: check data again. Parsing failed! soil_data2: Parsing successfully.  Write a python function that checks if the soil data is being entered correctly. Return True and print 'Parsing successfully' for correct data. Otherwise, return False and tells the user 'check data again. Parsing…

I need a code of this in C language. Input 1. Number of rows Constraints The value is guaranteed to be >= 3 and <= 100. Sample 3 2. Number of columns Constraints The value is guaranteed to be >= 3 and <= 100. Sample 3 3. Elements Description The elements of the multidimensional array depending on the number of rows and columns Constraints All elements are non-negative and are all less than 100. Output The first line will contain a message prompt to input the number of rows. The second line will contain a message prompt to input the number of columns. The succeeding lines will contain message prompts for the elements of the multidimensional array. Lastly, a blank line is printed before the rotated 90-degrees anti-clockwise 2D array.   For example this should be the output. Enter the number of rows: 3 Enter the number of columns: 3 Row #1: 1 2 3 Row #2:·4 5 6 Row #3: 7 8 9 3 6 9 2 5 8 1 4 7

Finding the common members of two dynamic arrays: Write a program that first reads two arrays and then finds their common members (intersection). The program should first read an integer for the size of the array and then should create the two arrays dynamically (using new) and should read the numbers into array1 and array2 and then should find the common members and show it. Note: The list of the common members should be unique. That is no member should be listed more than once. Tip: A simple for loop is needed on one of the arrays (like array1) and one inner for loop for on array2. Then for each member of array1, if we find any matching member in array2, we record it. Sample run:            Enter the number of elements of array 1:  7     Enter the elements of array 1: 10 12 13  10  14  15 12     Enter the number of elements of array 2: 5     Enter the elements of array 2:  17  12  10 19 12     The common members of array1 and array2 are: 12  10
