I just read the data, separating them into 2 groups, one for i<j and i>j for the other. And I sort them and compare them. I got AC for such a long time. Could you share your method?

### 10705 - The Fun Number System

Is there a good algo to solve it? I think brute force would take much time.

I didn't read your code completely. But I can tell you that the position of the card is constant. You can figure out by simple math.

Maniac wrote:why bother using doubles? Since rounding is truncating in this case, just use integers and use integer division:
[cpp]
int millisecs = ...;
int newmillisecs = (millisecs*125)/108;
[/cpp]
Simple as that....
why integer division doesn't cause error but does double using?

I use t=floor(temp*125/108*100), where t is long and temp is double. temp is the total seconds of given time in traditional format. But it didn't work. How do I improve it?

### 10683 - The decadary watch

Easy problem but got wa. I think the problem is the precision. How do I get the digits of the result precisely? Or are there some critical input?

I set the buffer to 3000 characters and get WA. I get PE after setting the buffer to 6000 characters. Than's strange. Now I don't know how to fix the PE.

Such a strange thing... I use 1E-5 as Epsilon and my program may output -0.000 and get PE. I get AC later by using 1E-4 as Epsilon and
-0.000 dissapeared!
