Re: 12920 - Patty's Gift

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 looking ...

Re: 11773 - King's Wish

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 4x4, si...

11773 - King's Wish

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?

262 Transferable Voting

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 sho...

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.

941 Permutations

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?

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 little jo...
