## Metric 

The evaluation metric for this competition is **Accuracy**. The Kaggle platform requires you to generate a submission text file that contains each test sample's `id`. We ask you to print the predicted sentiment (`0`: negative, `1`: positive) as the result. Please keep reading about the format of the submission text file.

## Submission Format
Your submission file should be in a `csv` (column separated value) format. The file extension is `.csv`. It should have two columns; `id` (note that the id here is the test sample filename) and `sentiment` (`0`: negative, `1`: positive) which you've predicted. The first row of your submission file is a header saying `id,sentiment` and the subsequent rows should contain the id that is sorted in ascending order. For example, your sample submission file should look like:

```
id,sentiment
0,1
1,0
...
```
