Table: Scores

+-------------+---------+
| Column Name | Type |
+-------------+---------+
| id | int |
| score | decimal |
+-------------+---------+
id is the primary key (column with unique values) for this
table.
Each row of this table contains the score of a game. Score
is a floating point value with two decimal places.


Write a solution to find the rank of the scores. The ranking
should be calculated according to the following rules:

The scores should be ranked from the highest to the lowest.
If there is a tie between two scores, both should have the
same ranking.
After a tie, the next ranking number should be the next
consecutive integer value. In other words, there should
be no holes between ranks.

Return the result table ordered by score in descending
order.

The result format is in the following example.


Example 1:

Input:
Scores table:
+----+-------+
| id | score |
+----+-------+
| 1 | 3.50 |
| 2 | 3.65 |
| 3 | 4.00 |
| 4 | 3.85 |
| 5 | 4.00 |
| 6 | 3.65 |
+----+-------+
Output:
+-------+------+
| score | rank |
+-------+------+
| 4.00 | 1 |
| 4.00 | 1 |
| 3.85 | 2 |
| 3.65 | 3 |
| 3.65 | 3 |
| 3.50 | 4 |
+-------+------+
