your operating system, and then proceed to follow the provided installation instructions.
Write MongoDB SQL scripts for below questions:
NOTE 1:
Before addressing the questions, please make sure you have set up a database named 'CSCI3287' in
MongoDB Compass. Inside this database, create a collection named 'HW6.' You can then proceed to
download the 'uscities.csv' file from the Canvas page and import it into the 'HW6' collection by clicking on
'Add Data' in the collections panel and then click on import JSON or CSV to import “uscities.csv” file.
NOTE 2:
Please utilize _MONGOSH, which is accessible within MongoDB Compass. You are allowed to employ filters
in the console solely for the purpose of verifying the query results. As part of your solution submission,
please submit query along with its corresponding output (result set).
