Update:

  • We are aware that some of you faced some issues with the problem SUM12. We will make a final decision on this on Monday. The current rankings are provisional and will be updated on Monday.
  • We are having an issue with our page caching.  You are not actually logged in as another user, the static html is being served incorrectly making the hello [username] appear incorrectly. Submissions are still being properly linked to your account, only the display in the top right corner is incorrect.  We are trying to resolve this shortly.  We apologize for the inconvenience thank you for understanding.
