Questions

1. - Write a program that will print three elements in an array whose sum is equal to a given number.

2. - I have some friends records in a text file (friends.json) -- one friend per line, JSON-encoded. I want to invite any friends within 100km of our Bangalore office which is almost like our home (GPS coordinates 12.9611159,77.6362214) for some food and drinks on us. Write a program that will read the full list of friends and output the names and user ids of matching friends (within 100km), sorted by user id (ascending).

The solutions are being disclosed only to show my ability to write good code. There are test suites, edge cases, modularity, etc in the solutions.
