Im very close to finishing this but the output im getting is:

can someone help me?

1. Query by Example JSON document store Query By Example allows a client to specify a structure which is used as an example, and all entities which match are returned. Implement a basic storage mechanism which allows a user to store documents in JSON format. The structure of the document may be otherwise arbitrary. The program accepts a command through stdin, followed by a space, followed by a document, followed by a newline. There are three allowed commands. add, store the given document .get, find all documents which have the same properties and property values as the given document, and emit them to stdout. delete, remove all documents which have the same properties and property values as the given document. The commands are all lowercase. Given the input: add ("1d":1,"last":"Doe","first":"John", "location":{"city":"Oakland","state":"CA", "postalCode":"94 add {"10":2,"last":"Doe","first":"Jane", "location": {"city":"San Francisco", "state":"CA", "postalCod add {"10":3,"last":"Black","first":"Jim", "location": {"city":"Spokane", "state":"WA", "postalCode":"9 add {"10":4,"last": "Frost","first":"Jack","location": {"city":"Seattle", "state":"WA", "postalCode":" get {"location":{"state" : "WA"},"active":true} get ("10":1) Emit: {"id":3,"last":"Black","first":"Jim","location": {"city":"Spokane", "state":"WA", "postalCode":"99267 Note that the documents must be output in the exact format as they were input. If multiple documents are matched, the documents must be emitted in the order they were created. The input may be rather complex and that the number of documents or the number of queries may be quite large.
