Thank you for using AtCoder. We have been publishing the test cases used in AtCoder contests via Dropbox, but we have temporarily suspended publication of the test cases due to inappropriate use by some users. We have provided the test cases to make it easier for users to review and study, but we have seen some uses that AtCoder did not originally anticipate, such as copying the AtCoder judge system to other environments. In order to prevent such uses, we are working to set restrictions on the use of the test cases. We sincerely apologize for any inconvenience this may cause to our users. We look forward to your continued support of AtCoder.
