Can anyone tell me what's wrong with my code? It gets WA. I handled the potential integer overflow problem with unsigned long long. I concatenated the [cost,recipe] to represent the cost of each recipe. Then I sorted it using qsort. I believe this handles the lexicographical order. Any ideas? Here's...

Does anyone know more ways to optimize this code? I already optimized my queue usage. I'm suspecting I can do my string concatenations faster, but I don't know how to do it. Any ideas how I can get this faster? Here's the code: #include <iostream> #include <string> //11234.cpp using namespace std; i...

Does anyone know if there's a limit on 'n' and 'm'?

traditionally, that extra blank line should've showed up as a presentation error. I guess this new judging system doesn't work the same way.

Likewise, I bet I have a silly mistake in here somewhere. I've been pulling my hair out trying to find out what it is. Anyone got any ideas?


note:
Since the score is always an integer, I avoided the use of doubles/floats

Thanks! That did the trick

In the old system, they used to e-mail the error message on compile errors. Now with this new system, they don't do that and there's no way to find out what's wrong with your code if you have a compile error on the judges' system but not on your own system.

Does anyone know why this gives a compile error? I compile by: g++ filename.cpp it works fine on my own pc, but it has a newer compiler. Does anyone know how to compile down to older versions? Thanks. #include <iostream> #include <string> using namespace std; string line; char num[100][100]; int ans...

Thanks! I got ACCEPTED.

It handles the above input cases exactly and it still gives me presentation error. My current program outputs a newline at the end of output. Weird thing is, if I remove that last newline at the end of the output, it'll say wrong answer. #include <iostream> using namespace std; string str [101]; voi...

Try using "long double" instead of "long int" and "fmod" instead of "%".

Why would that even be an issue? The problem clearly says "integers" as coconuts

Hi,

I'm wondering if someone can give some more sample inputs/output for this problem. I think my program is pretty good except maybe a few special cases.


Thanks

are you sure there is no solution for this case?

My program output says 2 people and 1 monkey.


My program is not AC

Thanks. I already fixed it. It was indeed some other bug. So for future reference, it is safe to assume exactly 22 integers in one input line.

In problem description says: The next 20 integers are the values of the first 20 cards in the deck. But that not true .... integers may be less .... Can someone verify this above statement? The problem specification says there will be "22" integers in a line. And that's what I'm assuming....
