Write a MongoDB query to find the restaurants which locate in a latitude value less than -95.754168.

Structure of 'restaurants' collection :

{
  "address": {
     "building": "1007",
     "coord": [ -73.856077, 40.848447 ],
     "street": "Morris Park Ave",
     "zipcode": "10462"
  },
  "borough": "Bronx",
  "cuisine": "Bakery",
  "grades": [

Note: This output is generated using MongoDB server version 3.6

Explanation:

The said query in MongoDB that finds all documents in the 'restaurants' collection where the value of the "coord" field inside the "address" subdocument is less than -95.754168.
The {"address.coord" : {$lt : -95.754168}} filters the documents where the value of the "coord" field inside the "address" subdocument is less than -95.754168. The $lt operator stands for "less than".

Previous: Find the restaurants that achieved a score is more than 80 but less than 100.
Next: Restaurants without 'American' cuisine that have a grade score over 70 and latitude below -65.754168 should be avoided.
