Can the sample data be explained:

Input
2 5 7 4 5.099

Output
7 4

My concern is, the distance from (2, 5) to (7, 4) is sqrt(26) = 5.099019514 which is greater than the given 5.099, so here is the case that if the string is shorter than the distance of the nails, what happends?

The problem is ...

Simple math deduction but tricky precision - not sure integeral process is required but my AC was depnending on it.

thanks Arif for the explanation.

can '9 1' cover a square smaller than 18x18?

Yes, it can cover, 9 x 9

right, i was aware of it. but for '9 1' i guess 9x9 is not the problem wants because '9 1' covers a length of the square.

the problem says '2 1' is valid for 4x4. while if '9 1' is valid for 9x9, '2 1' cannot be valid for ...

for the example input 18, how is an output '9 1' violating the problem statement?
it seems '9 1' is better than '9 2'
can '9 1' cover a square smaller than 18x18?

One thing should have been but not stated in the problem description that there are invalid candidate numbers in the ballots and ballots containing invalid candidates should be treated as spoiled.

the problem says,
However, the sorting should be according to the first 'ignored' letter. For Example if the email contains the line 'tid tim tis' then you should consider the three words as one word and print them as 'tis' (the last word in this group), but while producing the sorted output you ...

It seems the input is blended with some characters NOT within the base 64 set (upper cases, lower cases, digits, '+', '/', '=' and '#').
My code gets WA if I do not check the character set but got AC just after I filter the characters.

I got TLE submitting reasonable code (which I am quite confident to have it accepted). I doubted it was due to huge input but just after I submit a code doing nothing outputing just NOTHING at all, it got Accepted!

Is there any problem with the input?

I tried to reply to this thread but the topic is Locked so I could not reply.

Suggestions came to clear cookies to solve this problem. I tried it out but clearing cookies does not help, at least to my machine.

Does anyone meet the same problem?

Just immediately after upgrading to FireFox 2.0.0.7 as recommended also from the online judge front page, I cannot access the new online judge blocked by this message:

I think random test cases might not be helpful for tracing bug for this problem. Anyway, it's better than nothing to do.

what a twisted hobby of making simple things into vague descriptions. a problem setter at his position shall know lots of other ways to make hard problems, which are worth practicing and enjoyable. but problems like this are just like dream-murmuring ... sigh...

AC - thanks to little joey.

this problem has some un-reasonable tricks:

number 0 is treated as positive
number form like '+nnn' is not treated as a valid number
though it is friendly at some other points:

seems no line contains blank but all continuous characters
lines are not too long, as ...
