Polycarp likes to play with numbers. He takes some integer number $x$, writes it down on the board, and then performs with it $n-1$operations of the two kinds:

• divide the number $x$ by $3$ ($x$ must be divisible by $3$);
• multiply the number $x$ by $2$.

After each operation, Polycarp writes down the result on the board and replaces $x$

You are given a sequence of length $n$ — the numbers that Polycarp wrote down. This sequence is given in arbitrary order, i.e. the order of the sequence can mismatch the order of the numbers written on the board.

Your problem is to rearrange (reorder) elements of this sequence in such a way that it can match possible Polycarp's game in the order of the numbers written on the board. I.e. each next number will be exactly two times of the previous number or exactly one third of previous number.

It is guaranteed that the answer exists.
