# Time: O(nlogn)
# Space: O(1)
# X city opened a new cinema, many people would like to go to this cinema.
# The cinema also gives out a poster indicating the movies’ ratings and descriptions.
#
# Please write a SQL query to output movies with an odd numbered ID and
# a description that is not 'boring'. Order the result by rating.
#
# For example, table cinema:
# +---------+-----------+--------------+-----------+
# | id | movie | description | rating |
# +---------+-----------+--------------+-----------+
# | 1 | War | great 3D | 8.9 |
# | 2 | Science | fiction | 8.5 |
# | 3 | irish | boring | 6.2 |
# | 4 | Ice song | Fantacy | 8.6 |
# | 5 | House card| Interesting| 9.1 |
# +---------+-----------+--------------+-----------+
#
# For the example above, the output should be:
# +---------+-----------+--------------+-----------+
# | id | movie | description | rating |
# +---------+-----------+--------------+-----------+
# | 5 | House card| Interesting| 9.1 |
# | 1 | War | great 3D | 8.9 |
# +---------+-----------+--------------+-----------+
SELECT * FROM cinema
WHERE id % 2 != 0 and description != 'boring'
ORDER BY rating DESC;
