Problem I. IPv6 Address of Orz Pandas
*****
Announcement
The description of problem I is not very clear. In the preparation of the round all three staffs believed "shortest" means "with least number of remaining segments", unfortunately. So we failed to detect this issue. We found this issue in the training round and sent a clarification. But at that time the jury can't access Codeforces due to an unknown reason (maybe network down). The problem description would be updated. Sorry again for the issue.
