create and insert statements below:

create table subscriptions (user_id varchar(10),start_date date,end_date date);

insert into subscriptions values('U1','01-JAN-2023','31-JAN-2023');
insert into subscriptions values('U2','16-JAN-2023','26-JAN-2023');
insert into subscriptions values('U3','28-JAN-2023','06-FEB-2023');
insert into subscriptions values('U4','16-FEB-2023','26-FEB-2023');

We need to write a query that returns true/false for each user based on the overlapping of dates with other users. For instance, If user1's subscription period overlaps with any other user the query must return True for user1.
