Assume x contains at least one row and at least one column and j is a valid index in x. In plain English, what is being returned by the Java method below when it is called? 0; public static int f(int[] [] x, int j) { int p = 0; int i do { p+= x[j][i]; i++; } while (i < x[j].length); return p; } the sum of the values in the column at index i in x the sum...

Make the Sudoku algorithm for checking for duplicates to be Big -O of N, instead of N-squared. I.E. No nested for loops in rowIsLatin and colIsLatin. Only nested loop allowed in goodSubsquare. public class Sudoku { public String[][] makeSudoku(String s) { int SIZE = 9; int k = 0; String[][] x = new String[SIZE][SIZE]; for (int i = 0; i < SIZE; i++) { for (int j = 0; j < SIZE; j++)...
1)def toggle_cell(row, column, cells): • Return value: Flip the cell in the column of row from alive to dead or vice versa. Return True if the toggle was successful, False otherwise. • Assumptions: o cells will be a two-dimensional list with at least one row and one element in that row. o row and column are index values of cells • Notes: o Cells is being edited in place. Note that the return value is a Boolean and not a...

This is for Java. Create ONE method/function that will return an array containing the row and column of the largest integer i the 2D array. If the largest number is located on row 2, column 1, the method needs to return row 2 and column one. Do not use more than one method. Use the code below as the main. Please comment any changes. in java Given the main, create a method that RETURNS the largest number found in the...
