I keep getting "SubmissionErr". What does that mean ? What should I do ?

Thanks brianfry713.
I finally solved this problem by using merge sort.
I think this problem can also be solved by using segment trees. But I don't know how to do that.

First count the number of inversion in the left child.
Then count the number of inversion in the right child.
But then how do you ...

Can anyone give me some criticial test cases ? I keep getting WA

Thanks very much. Got AC

Thanks

I think the error comes from how my program does input.
How do you recognize a blank line from the input ?

My program passes all the test cases posted in the this forum.
However, I keep getting TLE
Can anyone give me some suggestion how to speed this up ?

I kept getting TLE on this problem.
Any suggestion to speed up my program ?
I used Kruskal algorithm.

@brianfry713: Thanks very much

Why does Uvatoolkit answer 1867505754 for the input "0x56F4FE05A" ?
Shouldn't the answer be 23342342234 ?

By the way, what is wrong with my code ? I keep getting WA

I removed "public" but I still got WA

Thank you so much.
You have helped me AC so many problems

I have tried all the test cases posted in this forum, but i still got WA.
Help me please. I feel so frustrated

Can someone help me figure out what is wrong with my code ?
This problem seems easy but long. I spent like almost 3 hours to make it. However, I kept on getting WA :(
Help me please.
