In the Java class MatrixHelix, implement the method int[][] helix(int[][]) that returns a matrix of identical dimensions to the input matrix, but with the contents in helix order. Your implementation should account for matrices of different sizes and should handle corner cases as well (0 x 0 matrices and 1 x 1 matrix, for example). Examples The matrix 1 2 3 4 5 6 7 8 9 would become 1 2 3 8 9 4 7 6 5 after the helix morph. The matrix 7 5 1 4 6 3 2 9 1 8 8 3 2 4 1 10 11 15 19 14 would become 7 5 1 4 6 4 1 10 11 3 2 14 19 15 2 3 8 8 1 9 after spiralizing. Implement all the methods that are indicated with //MODIFY THIS METHOD and // ADD TESTS TO CHECK PARTITIONS.

Question
In the Java class MatrixHelix, implement the method int[][] helix(int[][]) that returns a matrix of identical dimensions to the input matrix, but with the contents in helix order. Your implementation should account for matrices of different sizes and should handle corner cases as well (0 x 0 matrices and 1 x 1 matrix, for example).
Examples
The matrix
1 2 3
4 5 6
7 8 9
would become
1 2 3
8 9 4
7 6 5
after the helix morph.
The matrix
7 5 1 4 6
3 2 9 1 8
8 3 2 4 1
10 11 15 19 14
would become
7 5 1 4 6
4 1 10 11 3
2 14 19 15 2
3 8 8 1 9
after spiralizing.
Implement all the methods that are indicated with //MODIFY THIS METHOD and // ADD TESTS TO CHECK PARTITIONS.
