Well, I think a simple "Selection Sort" is Enough to get the minimum swaps (Someone please tell me if I am wrong!)

The Selection Sort will also solve the problem with Repeating numbers.

Not at all - it is always a pleasure to be able to help anyone!

I have run your code - you have two major faults!

First - you have to store the configurations ("BCG" etc) in a 4 element character array. When I run the code, i got this output BCGA 30. Remember, in C or C++, you have to use one ...

I cant spend much time to understand your code online(charge for using internet is a little high here) but one small thing - u have used a 3 element array to store the combination. But shouldn't it be that "BCG" needs a 4 element array to store its terminating NULL?

Your English is not too bad ...

Your code is too much complex i think- the problem is not so much complex.

I got WA with double but AC with Long Double.

I used natural log instead of base 10.

k = exp(log(p)/n) is enough to solve it.

best of luck

Okay I just found another of your request. You have asked for code. Do you really need the code? if so, tell me, i will give you mine.(I got an AC)

I think you have made a very much simple thing much complex. trying to simplify the code will do better.

Scanf returns the number of elements it scans - but sometimes i had it not working as i expected. though i am not sure, but your input-taking style may cause the problem. When scanf tries to ...

Is there any special case in 412?

I think the same as "Little John". the problem is itoa(). It is not supported in Linux/Unix.

Besides, you have to print exactly 13 digits for each binary number.

It will be better if you compile your programme usibg unix/linux before submission.

with best wishes

I have faced the same problem when I made my first submission to ACM.

You have placed @BEGIN_OF_SOURCE_CODE and @END_OF_SOURCE_CODE inside comments. Remove the comment markers and let them stay as a line.

the first lines will be like

/*@JUDGE_ID: ****** 000 "Whatever"*/
@BEGIN_OF_SOURCE_CODE ...
