Description

Write a SQL query to rank scores. If there is a tie between two scores, both should have the same ranking. Note that after a tie, the next ranking number should be the next consecutive integer value. In other words, there should be no "holes" between ranks.

+----+-------+

| Id | Score |

+----+-------+

| 1  | 3.50  |

| 2  | 3.65  |

| 3  | 4.00  |

| 4  | 3.85  |

| 5  | 4.00  |

| 6  | 3.65  |

+----+-------+

For example, given the above Scores table, your query should generate the following report (order by highest score):

+-------+------+

| Score | Rank |

+-------+------+

| 4.00  | 1    |

| 4.00  | 1    |

| 3.85  | 2    |

| 3.65  | 3    |

| 3.65  | 3    |

| 3.50  | 4    |

+-------+------+
