Competition question
Use a piece of SQL to give the calculation expression for poker 24 points
A detailed description
There is a table cards, id is the numeric primary key of the auto-increment field, and there are 4 fields c1, c2, c3, c4. Each field randomly selects an integer from 1 to 10, and the players are required to use a SQL to give 24 points. The calculation formula, the returned content example is as follows:
The result field is the calculated expression and only needs to return 1 solution. If there is no solution, result returns null.
Test data and verification process
1. Enter the NineData official website (www.ninedata.cloud), register and log in to the NineData platform;
2. Apply for a free mysql demo database;
3. View the cards table data in the SQL window: select * from poker24.cards.
Remark:

2. Only one SQL can be used, and built-in database functions can be used, but stored procedures/custom functions and code blocks cannot be used;
3. You can verify the correctness of SQL by yourself on the NineData platform demo database, or on your own database. The organizing committee’s evaluation server has a 4-core CPU and 32 GB memory;
4. Contestants must participate with integrity and are not allowed to submit other people's competition codes. If similar codes are found, the working group will consider the first one submitted as a valid entry;
