Problem Statement
We have two figures $S$ and $T$ on a two-dimensional grid with square cells.
$S$ lies within a grid with $N$ rows and $N$ columns, and consists of the cells where $S_{i,j}$ is #
.
$T$ lies within the same grid with $N$ rows and $N$ columns, and consists of the cells where $T_{i,j}$ is #
.
Determine whether it is possible to exactly match $S$ and $T$ by $90$-degree rotations and translations.
Constraints
- $1 \leq N \leq 200$
- Each of $S$ and $T$ consists of
#
and.
. - Each of $S$ and $T$ contains at least one
#
.
Input
Input is given from Standard Input in the following format:
