Of course only after the end of contest

For this task, pay attention to last few sentences.
>>Each subsequent value must be strictly less than the preceding one.<<
and
>>If several answers exist, output any of them. It is guaranteed that there is at least one consistent sequence.<<

Thanks a lot! I forgot that 1 test can be not like in statement. And I'll fix my mistake.
