Return the count of the number of elements in the 2D array words that have a length greater than the parameter len.

Important Note: Copy the following two methods into the window and don't change 
array2DLongWords.  CodingBat does not allow 2D array parameters, so this method is accepting 
the number of rows, number of columns, and a 1D array.  The first method takes this 
information and creates a 2D array named words that you will be using. The last parameter len
is the length that you will be checking each element against.  Enter your code into 
method array2DLongWordsB:

public int array2DLongWords(int rows, int cols, String[] array, int len)
{
	String[][] array2D = new String[rows][cols];
	int idx = 0;
	for (int r=0; r<rows; r++)
	{
		for (int c=0; c<cols; c++)
		{
			array2D[r][c] = array[idx];
			idx++;
		}
	}
	return array2DLongWordsB(array2D, len);
}

public int array2DLongWordsB(String[][] words, int len) { 
		
}
