Question

There's a "users" table that has more than 1M rows of "users" information. The image below are the first 3 rows.

Implement a SQL query that retrieves the "email" and "friend_count" of the "user_id" with the most friends.

**Understanding the Users Table Structure** The table below represents data from a user database. It lists several pieces of information for each user, such as their unique ID, username, email address, and the number of friends they have. **Table Data:** | user_id | username | email | friend_count | |---------|-----------------|--------------------------|--------------| | 3437315 | janedoe2.0 | janedoe2.0@email.com | 5 | | 3437316 | princessluv8996 | princessluv8996@email.com | 600017 | | 3437317 | sk8ter4l!f3 | sk8ter4l!f3@email.com | 583 | **Table Details:** - **Table Name**: users - **user_id**: Id of the user - **username**: name of the user - **email**: email of the user - **friend_count**: user's number of friends This table allows the database to manage and access primary information about users efficiently. Each column has a specific purpose: 1. **user_id**: Ensures uniqueness for each user. 2. **username**: Represents the chosen name or alias of the user. 3. **email**: Contact email for the user, which is also unique. 4. **friend_count**: Shows how many friends the user has within the system. This gives an idea of the user's social connectivity on the platform. Understanding and interpreting this table correctly are crucial for managing user databases in educational or social networking applications.
