Question
Implement the following method to sort the columns in a two
dimensional 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 double
values 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 ↵Enter
0.55 0.005 0.225 0.015↵Enter
0.30 0.12 0.4 0.008 ↵Enter
0.07 0.021 0.14 0.2 ↵Enter
The column−sorted array is
0.07 0.005 0.14 0.008
0.15 0.021 0.225 0.015
0.30 0.12 0.375 0.2
0.55 0.875 0.4 0.225

- A run is a sequence of adjacent repeated values. Write a program that generates a sequence of 20 random die tosses in an array and that prints the die values, marking the runs by including them in parentheses, like this: 12 (5 5) 3 124 3 (2 22 2) 3 6 (5 5) 6 3 1 Use the following pseudocode: 1. Set a boolean variable inRun to false 2. For each valid index i in the array A. If inRun If values[i] is different from the preceding value Print ) o inRun = false · If not inRun o If values[i] is the same as the following value Print ( inRun = true. Print values[i] 3. If inRun, print )arrow_forwardProblem2: A square matrix can be represented by a two-dimensionalarray with N rows and N columns. You may assume a maximum size of 50 rows and 50 columns. 1. Write an algorithm MakeEmpty(n), which sets the first n rows and n columns to zero. 2. Write an algorithm Add(M1, M2, M3), which adds two matrices M1 and M2 together to produce matrix M3. 3. Write an algorithm Subtract(M1, M2, M3), which subtracts matrix M2 from matrix M1 to produce matrix M3. 4. Write an algorithm Copy(M1, M2), which copies matrix M1 into matrix M2.arrow_forwardInput a list of employee names and salaries and store them in parallel arrays. End the input with a sentinel value. The salaries should be floating point numbers Salaries should be input in even hundreds. For example, a salary of 36,510 should be input as 36.5 and a salary of 69,030 should be entered as 69.0. Find the average of all the salaries of the employees. Then find the names and salaries of any employee who's salary is within 5,000 of the average. So if the average is 30,000 and an employee earns 33,000, his/her name would be found. Display the following using proper labels. i need to do this in raptor.arrow_forward
