## Print matrix in a sprial order

Recursive Solution (Java):

```public class PrintMatrixSpiral
{
public static void main(String[] args)
{
int[][] matrix =
{
{ 2, 4, 6, 2, 5, 7 },
{ 2, 5, 7, 8, 9, 3 },
{ 6, 4, 7, 3, 5, 7 } };

printSpiral(matrix);
}

public static void printSpiral(int[][] matrix)
{
printSpiral(matrix, 0);
}

private static void printSpiral(int[][] matrix, int depth)
{
if (matrix == null && matrix.length == 0)
return;
int rows = matrix.length;
int cols = matrix[0].length;
if (2 * depth > Math.min(rows, cols))
return;
for (int i = depth; i < cols - depth - 1; ++i)
{
System.out.print(matrix[depth][i] + ",");
}
for (int i = depth; i < rows - depth - 1; ++i)
{
System.out.print(matrix[i][cols - depth - 1] + ",");
}
for (int i = rows - depth; i > depth; --i)
{
System.out.print(matrix[rows - depth - 1][i] + ",");
}
for (int i = rows - depth - 1; i > depth; --i)
{
System.out.print(matrix[i][depth] + ",");
}
printSpiral(matrix, ++depth);
}
}

```
