Rotate 2D Array 180 and 90 | Dataford Interview Questions

How would you rotate a 2D array 180 degrees and 90 degrees?

Implement rotate_matrix(matrix, degrees) for a non-empty rectangular matrix. Return a new matrix rotated clockwise by either 90 or 180 degrees, without modifying the input matrix. A 90-degree rotation may change the matrix dimensions.

Constraints

1 <= number of rows <= 100
1 <= number of columns <= 100
The matrix is rectangular, so every row has the same length
degrees is either 90 or 180
Matrix values are integers

Function Signature

def rotate_matrix(matrix, degrees):
