For those who keep on getting TLE... I just reallized that my algorithm ( which was also O( 2 * n^3 ) ) kept on getting TLE just beacuse I used C++ strings. I usually scanf into a buffer and than write something like: string s = buff; In my code, I only used the [] operator and it was TLE. Then, ins...

The last input is not legal because it is unsorted, so the output is also wrong. When you sort it, the correct output is 5.40

In the third input from the end, the clouds start at (1, 7), but they should always start at (0, y) and mountains are longer than clouds, so this is also an illegal input.

Could someone write here the 6 intersection sets in the last example in the sample input? I only find 2 of them, no matter what I do ( I even searched for sets using O( 2^n ) algorithm ). Those I find are: 0 3 4 7 1 2 5 6 ( edit ) I realize my mistake now... I thought the first number was the number...

I had the same output when i did topological sort. This is the key sentence: In the case there is no relation between two beverages Dilbert should start drinking the one that appears first in the input. It means that because juice is the first drink in the input that isn't preceeded by some other dr...

got ACC, thanks

It seems my code has a bug somewhere... I was affraid it was precision error, but this is much easier to solve

One more question: does the opponent always use maximum allowed number of soldiers?

Thank you very much!

Could someone give me your outputs for these inputs?

Does the judge use -O2 option when compiling c++ code?
My code runs signifantly slower when compiled without -O2

I am also getting TLE, but my code runs in about 1.36 seconds for ten test cases where n = 5000 on my laptop. There are at most ten test cases, and at most 5000 points ( I've checked this ), so it should be ACC on the judge. I don't believe my laptop is 10 times faster than the judge server :) Here ...

I didn't explicitly take care of printing +0.000 or -0.000, and got P.E.
I solved one problem here on ACM in which you have to judge some outputs. It stated that if al numerals are correct, but some letters are wrong, this is considered P.E. I believe this is the case here.

I am trying to solve this problem, but I can't get ACC. I hate this kind of problems, but would really like to solve this one. (personaly, this is one of the most ugly problems I have ever seen) Please, post some inputs and clarifications ( if you can think of any ) because I am doing something wron...

Which years before doors are considered leap? Those like 4bd or those like 5bd? I am asking because for example, 5bd is 8 years before 4, which is a leap year.

Thanks!
