Just unblocked this challenge and took 2 top solutions out of you list and copy-pasted it as my submissions, and compared them to the last solution I submited before unlocking.
I guess running conditions are changed - and even those who once had 100 points - are failing now ( note that running times of my solution in other cases are bit -like 20%- lower than these top solutions).
My claim is ,that test #7 was pushed too far - it might depend on the server load or more likely disk speed of server running test cases.
Moreover it is unusable by human beings(or even by some IDEs)
Below the mentioned results.
My solution
- submited before unlocking ranked 62.69 points.
Same here with Java. I could not pass the 7th test case for days and I unlocked the solutions, wich got 100 points. Run them - they timeout on the 7th test case as well.
Conceptially these solutions are the same as my. Some contain custom input stream readers, which of course improves the performance, but is not the point of the excersize (and it does not help anyway).
The test cases should be designed better. If you came up with a dicent algo and did not do any stupid implementation errors then it should pass.
Oh, that's just a joke! One of those 100 points solution in Java did pass only 3 test cases. On other 3 I got "Wrong answer" and 2 timed out. That's a 100 points? Really?
My solution just couldn't make the 7th test case in time and I've decided to sucrifice my points to unveal the "wisdom of the top-coders" and this is what I got!
This is just not fair.
I did not check all the solutions, but for now it seems like those, who got 100 points were just luckly to submit before test cases were added.
Which, I believe, is not correct. The solutions should re-run when a new test-case is added and points should be re-evaluated.
