Chessman

There's an n × 1 chessboard filled with some chessman, where n is infinity. For each chessman, you can make any move of the following:

1.Jump to the 4th grid on the right or left, if that grid is empty. For example:
...*........
=>
.......*....

...****.....
=>
....****....

....*.**....
=>
...**.*.....

2. Jump to the 3rd grid on the right, if that grid is empty, as well as the second and the first grid on the right has and has not a chessman respectively. Then, after this the junp is taken, the first grid the chessman jumped over will have a chessman, and the second grid the chessman jumped over will be empty. For example:

...*.*.....
=>
....*.*....

3.Jump to the 2nd grid on the right, if that grid is empty and the grid the chessman is about to jump over has a chessman. Then, the grid the chessman jumped over will be empty. For example:

...**.....
=>
.....*....

Given the first 30 girds on the left (has or has not chessman) of two chessboards, the rest grids being all empty, decide whether the first chessboard can be changed to the second chessboard with those three kinds of moves listed above?

The first line of the input is the number of test cases. For each case there are two lines. Each line contains 30 characters. '.' represents empty grid. '*' represents a chessman. There is a blank line before each test case.
