For each id in the test set, you must predict a type of class (or label). The file should contain a header and have the following format:

```csv
Id,Expected
paper/paper_1775.jpg,0
paper/paper_1749.jpg,0
.....
```

The expected numeric class labels are assigned based on a predefined order rather than alphabetical sorting. The class labels are mapped as follows:
Paper → 0
Clothes → 1
Metal → 2
Cardboard → 3
Trash → 4
Glass → 5
Biological → 6
Battery → 7
Plastic → 8
Shoes → 9
