\n\n

 

\n\n

A country is big if:

\n\n\n\n

Write an SQL query to report the name, population, and area of the big countries.

\n\n

Return the result table in any order.

\n\n

The query result format is in the following example.

Example 1:

\n\n
\nInput: \nWorld table:\n+-------------+-----------+---------+------------+--------------+\n| name        | continent | area    | population | gdp          |\n+-------------+-----------+---------+------------+--------------+\n| Afghanistan | Asia      | 652230  | 25500100   | 20343000000  |\n| Albania     | Europe    | 28748   | 2831741    | 12960000000  |\n| Algeria     | Africa    | 2381741 | 37100000   | 188681000000 |\n| Andorra     | Europe    | 468     | 78115      | 3712000000   |\n| Angola      | Africa    | 1246700 | 20609294   | 100990000000 |\n+-------------+-----------+---------+------------+--------------+\nOutput: \n+-------------+------------+---------+\n| name        | population | area    |\n+-------------+------------+---------+\n| Afghanistan | 25500100   | 652230  |\n| Algeria     | 37100000   | 2381741 |\n+-------------+------------+---------+\n

\n\n

如果一个国家满足下述两个条件之一，则认为该国是 大国 ：

\n\n
    \n\t
  • 面积至少为 300 平方公里（即，3000000 km2），或者
    • \n\t
  • 人口至少为 2500 万（即 25000000）
    • \n
\n\n

编写一个 SQL 查询以报告 大国 的国家名称、人口和面积。

\n\n

按 任意顺序 返回结果表。

\n\n

查询结果格式如下例所示。
