#### Contest format:↵
↵
- You will have to solve **7** tasks in **2** hours and **30** minutes.↵
- There will be full feedback throughout the entire contest.↵
- Tasks will not have partial scoring, so you need to pass all test cases for a solution to count (ACM-ICPC-style).↵
- Tasks will have dynamic scores. According to the number of users that solve a problem the score will vary between 100 and 1000.↵
- Besides the score, each user will also get a penalty that is going to be used as a tie breaker. ↵
↵
#### About the penalty system:↵
↵
- Computed using the following formula: the minute of the last accepted solution + the penalty for each solved task. The penalty for a solved task is equal to log2 (no_of_submissions) * 5.↵
- Solutions that don't compile or don't pass the example test cases are ignored. ↵
- Once you solve a task you can still resubmit. All the following solutions will be ignored for both the score and the penalty.↵
↵
The CSA team still recommends using an updated version of Google Chrome. If you find any bugs please email them at contact@csacademy.com
