I got the below error during the contest.
The last executed test case was displayed incorrectly. It was due to a glitch in the format of the input, which I've just fixed. Now it should display the correct last executed test case.
As for the contest result, I agree that it did cause some inconvenience as you can't rely on the last executed test case to debug your code. However, it is still fair for every participant since this glitch is the same for everyone.
