Provide a string with the found hidden message for each index representing a file number from [Discussion tab](https://www.kaggle.com/competitions/detect-leaking-data/discussion). The important part is that the value in the second column is of type string, which cannot be empty. You can also provide " " in the second column for test purposes. An example can be seen below:

| id | hidden_message|
| --- | --- |
|1|     |
|2|Some answer 1|
|3|Some answer 2|
|4|Some answer 3|
|5|Some answer 4|

The file should be saved in CSV.
