Submissions are evaluated on [Accuracy](https://scikit-learn.org/stable/modules/generated/sklearn.metrics.accuracy_score.html) between the predicted plaintext `index` and the actual `index`.


## Submission File
For each ciphertext in the test set, you must predict the plaintext index. The file should contain a header and have the following format:

    ciphertext_id,index

    ID_aab1e107a,0
