A country is big if it has an area of bigger than 3 million square km or a population of more than 25 million.

Write a SQL solution to output big countries' name, population and area.

For example, according to the above table, we should output:

    +--------------+-------------+--------------+
    | name         | population  | area         |
    +--------------+-------------+--------------+
    | Afghanistan  | 25500100    | 652230       |
    | Algeria      | 37100000    | 2381741      |
    +--------------+-------------+--------------+
