Solution

The language used in the problem statement is SQL. Here is the solution:

DELETE FROM Customers WHERE customer_id = 304;

This SQL query will delete the record of the customer with customer_id 304 from the Customers table.

Please note that the time and space complexity of this operation is not O(N^2) as mentioned in the problem statement. The complexity of a DELETE operation in SQL depends on many factors such as the database management system, the indexing of the table, etc. However, in general, if the table is indexed on the customer_id column, the DELETE operation would have a time complexity of O(log N) because it's a binary search operation.
