It's ambiguous to me at least whether you can change the order of the sequence or not.
like {a3, a1, a5, a7}, {a6, a2, a4, a8} Read the problem again.
Set is given. so ordering is not taken into account.
However WA34 now :( In the example outputs there's no third line containing the geometric progression like the problem states there should be. WA#29
ant hint for this tricky test case?
I make lots of random cases but still no help :-( For this particular problem I think the input size matters. It allows getting 0.001 sec on every test after few retries. But it makes it hard to get 0.001 sec on all tests in a single try. |
