What is the output of the following code:   int arr[4][4] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16}; for (int j = 2; j < 3; j++)     for(int i = 0; i < 4; i++)         cout << arr[i][j];

Consider the following code segment.  int[][] mat = new int[4][6]; for (int r = 0; r < 4; r++)  {   for (int c = 0; c < 6; c++)    {     if(c < 3 - r || c > 3 + r)      {       mat[r][c] = 0;     }      else      {       mat[r][c] = 1;     }   } } Which of the following represents mat after this code segment is executed?

Consider the following method. public static int operation(int[][] mat)  {   int currentVal = mat[0][0];   int result = 0;   for (int j = 0; j < mat.length; j++)    {     for (int k = 0; k < mat[j].length; k++)      {       /* missing code */     }   }   return result; } Which of the following should replace /* missing code */ so that the method returns the index of the column which contains the smallest value in the two-dimensional array?

Consider the following method public static int[][] operation(int[][] mat, int[] vec, int c) { int[][] result = new int[mat.length][mat[0].length]; for (int j = 0; j < mat.length; j++) { for (int k = 0; k < mat[j].length; k++) { if (k == c) { result[j][k] = mat[j][k] + vec[j]; } else { result[j][k] = mat[j][k]; } } } return result; } The following code segment appears in another method in the same class. int[][] m = {{1, 2, 3, 4}, {4, 3, 2, 1}, {2, 1, 3, 4}, {1, 3, 2, 4}}; int[] v = {4, 4, 4, 4}; int[][] grid = operation(m, v, 1);   Which of the following represents the contents of the grid as a result of executing the code segment?
