26498번 - Snowflakes 다국어

문제

Snowflakes can be symmetrical both vertically and horizontally. Snowflakes that aren’t symmetrical are useless. A snowflake is essentially a two dimensional array of features. A feature is a single digit between 0 and 9. Horizontal symmetry occurs if you flip the snowflake horizontally. It is still the same snowflake. Likewise, vertical symmetry is defined in the same way. A snowflake is “Beautiful” if its horizontally symmetrical, “Graceful” if its vertically symmetrical, and “Magnificent” if it is both. Otherwise it is “Useless”. For each snowflake, print what kind of snowflake it is.
