The program will print `(20, 3)`. The array is a 3-dimensional array with shape `(10, 20, 30)`. The expression `array[0, :, idxs]` takes the first element of the first dimension, all elements of the second dimension, and the elements of the third dimension specified by the list `idxs`. The resulting array has shape `(20, 3)`.

The program will print the shape of the array `array[0, :, idxs]`. The array `array` has a shape of `(10, 20, 30)`, meaning it has 10 rows, 20 columns and 30 channels. The array `array[0, :, idxs]` is a slice of the array `array` that takes the first row, all the columns and the columns specified by the list `idxs`, which contains the values 1, 2 and 3. Therefore, the shape of the array `array[0, :, idxs]` will be `(30,)`, as it has 30 channels and only one row and one column. So, the program will print the following output:
1 | The array shape is (30,) |
