Create a new public static method called ‘isLatinSquare’ that passes in a two-dimensional array. This new method will return ‘true’ if the passed array is a Latin Square. ** SHOULD only be 1 or 2 lines of code

Expert Solution

public static boolean isLatinSquare(int[][] matrix) // Public method isLatinSquare where the return type is boolean

{

boolean[][] row_temp = new boolean[matrix.length][matrix.length]; // Two dimensional array declaration

boolean[][] column_temp = new boolean[matrix.length][matrix.length]; // Two dimensional array declaration

for (int i = 0; i < matrix.length; i++) { // Running in loop

if (matrix[i].length != matrix.length) // Condition checking

return false; // Return type

for (int j = 0; j < matrix.length; j++) { // Running in loop

int index = matrix[i][j] - 1; // Performing the operation

if (row_temp[i][index] || column_temp[j][index]) // Condition checking

return false; // Return type

row_temp[i][index] = column_temp[j][index] = true;

}

return true; // Return type

}

Hope this helps.

In Java. Create a class called FileSumWrapper with a method that has the signature public static void handle(String filename, int lowerBound) Make this method call FileSum.read and make your method catch all the errors. FileSum.read is a method that takes a filename and a lower bound, then sums up all the numbers in that file that are equal to or above the given lower bound. FileSum : import java.io.File; import java.rmi.UnexpectedException; import java.util.Scanner; public class FileSum { public static int...

Create a method: Public Static boolean isSubArray489(int[] intArray) This method has an array of integers as its input parameter, we'll say that a SubArray 9,8,7is that three integers, 9,8,7values appearing decreasing order one by one in the array. Return true if the array does contain any SubArray “987” Notice that any 3 integers that presenting a decreasing by one order must return True. (987, 876,765,654, 543, 432,321, 210 are all True) Call this method in your main function, and pass in...

Create a class called “Array” that implements a fixed-sized two-dimensional array of floating-point numbers.

Programing in Scala language: Create a class called “Array” that implements a fixed-sized two-dimensional array of floating-point numbers. Write separate methods to get an element (given parametersrow and col), set an element (given parametersrow, col, and value), and output the matrix to the console formatted properly in rows and columns. Next, provide an immutable method to perform array addition given two same-sized array.

Create a class called FileSumWrapper with a method that has the signature public static void handle(String filename, int lowerBound). Make this method call FileSum.read and make your method catch all the errors. FileSum.read is a method that takes a filename and a lower bound, then sums up all the numbers in that file that are equal to or above the given lower bound. I'm unsure at how to incorporate the FileSum.read() method to even start anything. I also don't know...

C++ ASSIGNMENT: Two-dimensional array Problem Write a program that create a two-dimensional array initialized with test data. The program should have the following functions: getTotal - This function should accept two-dimensional array as its argument and return the total of all the values in the array. getAverage - This function should accept a two-dimensional array as its argument and return the average of values in the array. getRowTotal - This function should accept a two-dimensional array as its first argument...

you will create a dynamic two dimensional array of mult_div_values structs (defined below). The two dimensional array will be used to store the rows and columns of a multiplication and division table. Note that the table will start at 1 instead of zero, to prevent causing a divide-by-zero error in the division table! struct mult_div_values { int mult; float div; }; The program needs to read the number of rows and columns from the user as command line arguments. You...

Create a “Main” method that contains two 2-Dimensional arrays of characters. The first array, which we will call our visible field, needs to be 5 by 5 and should initially hold the underscore character “_”. This will be used in our game of minesweeper to represent the possible locations the player can check. The second array, which we will call our hidden field, should also be 5 by 5 but filled with the capital letter "S” which means safety. However, we...

Write two methods. The first method is randFill2DArray. This method will fill a two-dimensional array with random integers between a given min and max value. It must accept for parameters, min and max values for the creation of random integers, and rows and columns for the number of rows and columns of the array. The method should return an array of rows by columns size, filled with random integers between min and max values. The second method is called printRA,...
