We have some customer records in a text file (customers.json) -- one customer per line, JSON-encoded. We want to invite any customer within 100km of our Dublin office for some food and drinks on us. Write a program that will read the full list of customers and output the names and user ids of matching customers (within 100km), sorted by User ID (ascending).
- You can use the first formula from this Wikipedia article to calculate distance. Don't forget, you'll need to convert degrees to radians.
- The GPS coordinates for our Dublin office are 53.3381985, -6.2592576.
- You can find the Customer list here.
