The evaluation metric for this competition is weighted classification accuracy. You can think of the entire challenge as a multiclass classification problem where each challenge has a weight (difficulty) and unique label (flag). Instead of building a classifier to get the right accuracy, you're going to capture the flags.

**Flags are unique to each person solving a challenge.** Please respect the spirit of the competition and do not share flags. Teams found sharing flags or using shared flags will be disqualified!

## Submission Format

Submission files should contain two columns: `challenge_id` and `flag`. The file should contain a header and have the following format:

There should be 22 rows (not counting the header).
