Understanding the Big Countries Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Table: World +-------------+---------+ | Column Name | Type | +-------------+---------+ | name | varchar | | continent | varchar | | area | int | | population | int | | gdp | bigint | +-------------+---------+ name is the primary key (column with unique values) for this table. Each row of this table gives information about the name of a country, the continent to which it belongs, its area, the population, and its GDP value. A country is big if: it has an area of at least three million (i.e., 3000000 km2), or it has a population of at least twenty-five million (i.e., 25000000). Write a solution to find the name, population, and area of the big countries. Return the result table in any order. The result format is in the following example.
