Problem C
Folding a Cube

It is well known that a set of six unit squares that are attached together in a “cross” can be folded into a cube.

But what about other initial shapes? That is, given six unit squares that are attached together along some of their sides, can we form a unit cube by folding this arrangement?

Input

Input consists of $6$ lines each containing $6$ characters, describing the initial arrangement of unit squares. Each character is either a ., meaning it is empty, or a # meaning it is a unit square.

There are precisely $6$ occurrences of # indicating the unit squares. These form a connected component, meaning it is possible to reach any # from any other # without touching a . by making only horizontal and vertical movements. Furthermore, there is no $2 \times 2$ subsquare consisting of only #. That is, the pattern

Output

If you can fold the unit squares into a cube, display can fold. Otherwise display cannot fold.
