fix the errors in the following code public class Test { public static void main(String[] args) { int[][] matrix = {1, 2, 3, 4, 5, 6}; System.out.println(m(matrix, 1)); } public static int m(int matrix, int column) { int sum = 0; for (int i = 0; i < matrix.length; i++) sum += matrix[i][column]; return sum; } }
