Oh darn. Yes, I realized that the second testcase up there is incorrect, but I didn't realise that the first testcase said 10 instead of 12.

I officially messed the testcases for this question up. I apologize. I believe I uploaded the un-updated version of the testcase. I'll make sure that this doesnt happen again (mainly because the rest of the DWITE's won't overlap with my exams).

Once again, my bad.

I have uploaded the fixed testcase for #5 here: http://www.sendspace.com/filegroup/3Ci3P9Q6KjMX0hVn5UsSwQ. Feel free to run your last submission to #5.

Is it just me....or does the input file have a line of underscores?

wow, Ok so I copied the data and fixed the 10 to a 12 and then ran my program while I did a few other things. After leaving it for 10 minutes I killed it. Wow that is a massive test case. It would take a second of your runtime just to read it all

I don't think DWITE's judge used underscores. A bunch of those inconsistencies is due to this test set simply being too large.

I added the underscores so that you can view the 5 separate testcases more easily. The actual underscores were removed when uploaded onto the judge.

I noticed this today when I was trying to figure out why Judge DWITE always told me I was running with errors. Kudos to the people that got two test cases correct on that question by (probably) ignoring the given number of commands altogether.

As a side note, was the huge dataset the reason why the server was going down pretty heavily after the contest? I did manage at one point to get in and see the dataset (at which point it wasn't just pointing to a link), as I imagine did others... and when you're busy serving up a 26 MB file to everyone who makes it to that link, I imagine it would be pretty tough to keep serving everyone else.

@lufthansa747- That's odd. There should be a word 'cpjfhefag...' after that. Perhaps an issue with the test file I sent you. Merely add the first word in the next line as the second word (i.e. all the portals form a chain in this case).

Yup, that's exactly what happened. Which is also why the availability of the testcase was removed shortly after.

The testcase should be back up by now, but it is a link to a file rather than a 26MB html file of death.

Even still it took a few minutes to load the test case of death then copy pasting it into a text file took another while. I really enjoyed in the past when worst possible case isn't ACTUALLY in the dataset Very Happy
