Write a SQL query to delete all duplicate email entries in a table named Person, keeping only unique emails based on its smallest Id.

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

| Id | Email            |

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

| 1  | john@example.com |

| 2  | bob@example.com  |

| 3  | john@example.com |

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

Id is the primary key column for this table.

For example, after running your query, the above Person table should have the following rows:

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

| Id | Email            |

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

| 1  | john@example.com |

| 2  | bob@example.com  |

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

Note:

Your output is the whole Person table after executing your sql. Use delete statement.
