You are required to submit:

1.      The SQL statements for each query, which should be copied from your SQLite3 Command Line and pasted into your submission file. If you type .echo on at the SQLite3 Command Line, SQLite will output your SQL statement with the results of the query making it easy to copy and paste both.

2.      The screenshots of the results of the SQL statements which are to be copied from your SQLite3 Command Line and pasted into your submission file immediately after you execute the SQL query. If you used an output file please submit only the output file.
