A Bangladeshi Contest's problem F testdata.

[Petr]

Please recheck it. I strongly believe there are negative answers in reference solution output.

There is no negative output in the test data I sent. But may arise while truncating. The judge data had to made small as the judge was too slow for the original judge data. Also there may be some precision problem. I have sent an special judge, I hope this problem will be rejudged soon.

This problem did not have any special judge initially but don't ask me why.

Shahriar, can you send it to me? Maybe Miguel is quite busy now. Thanksa lot!!

Input will be terminated with N=0 and K=0.

But, the sample does not show it. What will be the right thing?

[Carlos]

Corrector program is working now, and the two 0's have been added to the sample input.
