- In java, please read the text file as array. Then, replace the null with 0 and calculate the sum of the new students in ABC University.Example of text file: (university,year,total_students,new_students,new_staff,ABC, 2000, 3457, , ,ABC, 2001, 3675,218, ,EFG, 2000, 2389,602, ,EFG, 2001, 2785,396, 65,)Write a method that returns the sum of all the elementsin a specified row in a matrix using the following header:public static double sumRow(double[][] m, int rowIndex)Point Write a test program that reads a 3-by-4 matrix and displays the sum of each row.Here is a sample run:Enter a 3−by−4 matrix row by row:1.5 2 3 4 ↵Enter5.5 6 7 8 ↵Enter9.5 1 3 1↵Enter Sum of the elements at row 0 is 10.5Sum of the elements at row 1 is 26.5Sum of the elements at row 2 is 14.5For this part you should write a java program to generate a ?x? random real (type double) matrix which elements are random real numbers between ? and ?, where ? and ? are respectively row and column indices of the element. Your program should take ? and ? via keyboard entry and print the matrix row-by-row in the console. Develop you program based on the provided sample result below. PLEASE NOTE THAT that the numbers generated should be between the postion of the matrix. For instance in the output, if the position is 2nd row 3rd column the number in that position (2nd row 3rd column ) should be between 2 and 3 .
- Q5. Write a program that reads from the user an integer matrix with 10x10, and then rotate that matrix 180° (UPSIDE DOWN) after that, calculate the sum and the average of the main diagonal. Print the matrix after the rotation and the values of the sum and the average of the main diagonal.In Java Write a program that counts the number of occurrences of lowercase and uppercase vowels inentered lines of text. Use a two-dimensional array to store the vowel counts. The array’s firstcolumn holds the counts for the lowercase vowels, and the second column holds the counts forthe uppercase vowels.The user indicates the end of the input by pressing enter by itself. At that point, your programshould print, for each vowel, the total number of lowercase occurrences, the total number ofuppercase occurrences, and the total number of combined occurrences.Here are some implementation requirements:1. Use two separate files – one for a main driver method and one for a VowelCounter classthat keeps track of vowel counts.2. main – Repeatedly prompt the user to enter a line of text or press enter by itself to quit.Note that the stdIn.nextLine() method returns the empty string ("") if the user pressesenter by itself. For each entered line of text, call the processLine method. When the…Write a method that returns the sum of all the elements in a specified column in a matrix using the following header: public static double sumColumn (double[][] m, int columnIndex) Write a (test) program that reads a 3-by-4 matrix and displays the sum of each column. Here is a sample run: Enter a 3-by-4 matrix: 1.5 2 3 4 5.5 6 7 8 9.5 1 3 1 Sum of the elements at column 0 is 16.5 Sum of the elements at column 1 is 9.0 Sum of the elements at column 2 is 13.0 Sum of the elements at column 3 is 13.0
- A minimax or saddle point in a two-dimensional array is an element that is the minimum of its row and the maximum of its column, or vice verse. For example, in the following array11 22 33 33 99 55 66 77 77 44 99 22the element 33 is a minimax because it is the maximum of row 0 and the minimum of column 2. The element 55 is another minimax because it is the minimum of row 1 and the maximum of column 1.Write a program that reads a 4-by-3 matrix, and then prints the location and value of each minimax in the matrix. For example, it would printa[0][2] = 33 is a minimax a[1][1] = 55 is a minimaxfor the matrix shown above.Implement the following method to sort the columns in a twodimensional array. A new array is returned and the original array is intact.public static double[ ][ ] sortColumns(double[ ][ ] m) Write a test program that prompts the user to enter a 4 X 4 matrix of doublevalues and displays a new column-sorted matrix. Here is a sample run: Enter a 4−by−4 matrix row by row:0.15 0.875 0.375 0.225 ↵Enter0.55 0.005 0.225 0.015↵Enter0.30 0.12 0.4 0.008 ↵Enter0.07 0.021 0.14 0.2 ↵EnterThe column−sorted array is0.07 0.005 0.14 0.0080.15 0.021 0.225 0.0150.30 0.12 0.375 0.20.55 0.875 0.4 0.225create an array of 30 random numbers that range between 1and 100. And yet again, write a function that will receive a number from the userand determine if that number exists in the array or not. But this time, start bySORTING your input list. After a sort, the list in problem 1 is as follows:[2, 2, 3, 5, 12, 14, 14, 15, 23, 36, 39, 41, 44, 44, 45, 48,49, 50, 52, 52, 59, 71, 81, 82, 88, 89, 89, 93, 96, 97] Approach: Implement a method called findC(x, A, i, j), where x is the number we arelooking for in array A, the first index of the array is i and the last index is j. We wantto determine whether x exists in A anywhere between index i and index j. Your firstcall to this method will therefore look like this: findC(x, A, 0, A.length-1). In the body of your function, compare x with the item that is in the middle of thearray, as you did before. As before, call the middle of index of the array mid. But thistime, if x<=a[mid], recursively call your function to search ONLY the first half of…
- Exercise 1: Write a program that generates a sequence of 20 random values between 0 and 99 in an array, prints the sequence, sorts it, and prints the sorted sequence. Use the sort method from the standard Java library. Exercise 2: Write a program that stores a list of countries: "Egypt", "Switzerland", "Argentina", "Spain", "Portugal", "Luxemburg", etc. Initialize your array with a single statement. Then print out the array. Use the sort function as before to sort the countries in alphabetical order. Reprint your array. Exercise 3: Implement exercises 1 and 2 using ArrayList. Use the Collections.sort method for sorting. After you have printed and sorted your results, then append an additional element to each list and reprint your ArrayLists. Notice that the new items will appear just at the end and will not be sorted. Resort and print out the new ArrayLists again. To clarify, you should print out your ArrayLists after your first sort, after adding items with the…In Python, grades = {'Tim': [87,96,70], 'Sue': [100,87,90], 'Jack': [94,77,90], 'Kevin': [100,81,82], 'Bart': [83, 65, 85]} Ask user to enter the names of the rows, i.e., indices. You can use: len(grades) to get the number of rows of the DataFrame. In addition, using the sort_index() method, ask user whether they wish to sort by rows or by columns and whether to sort in ascending or descending order (do not use any if-else statements) '''Please Help Write a program to ask the user for the number of arrays he wants to maintain and then populate eacharray by taking elements from the user. Merge all these arrays in another array and finally remove duplicateelements from the merged array.
