During the first minutes of AtCoder Beginner Contest 129, some of the input files for Problem C on the judge servers were malformed, which caused incorrect verdicts on some submissions. We will take the following measures to deal with this issue. If you think you were affected by this issue, please send the following information from the “Clarification” tab by June 11, 23:59(JST): - The URL of your submission for Problem C which was initially judged as wrong but rejudged as correct - The amount of time you think you wasted because of this issue We will decrease the submission times of your later submissions by at most (21:27:00 JST - the submission time for Problem C). We will temporarily update the participants’ ratings, but we will update them again after these measures have taken. We apologize again for the trouble.
