WEIGHING - Weighing

You have a double-pan balance, some object and a collection of weights. Mass of the weight is always a power of 3 (so: 1, 3, 9, 27, 81...). For each integer k>=0 there is only one weight with mass 3k. The object was put on the left balance pan. Your task is to put some weights on the left and right balance pans in order to make it balanced.


The first line of the standard input contains one integer t (t<101) which is number of test cases.

In each of the next t lines there is one number n (n<=109) which is the weight of the object.


For each test output consists of three lines. In the first line print number of weights (number x) and then print x numbers which you have to put on the left balance pan in ascending order. The second line should involve information about the right balance pan in the same format. Third line is a blank one.

Looks like java is back on track now :)

The right person has been informed.
; but for example ranking on polish SPOJ is off and won't be fixed in few weeks (sic!). So I wouldn't be optimistic.

Piotr: looks like spoj is broken after the upgrades. Can't get my java solution to even compile. On it worked with "class Main{...", but even that won't work here :(

Thank You for Your remarks. :-)

You should clarify that
1) n = weight of object, and
2) the first line of output is what you must put on the left pan, and the second line of output is what you must put on the right pan.
