needs more test cases, I was able to pass by returning manually counted number of expected islands

I had a go at it (a very very long one). I was forced to get help from a java-oriented solution using something called Depth-first-search. today is a very sad day for me :(

I think 6kyu is just about right

id rate this a 7kyu

@Eluderei he obviously knew that but didn't know what to map to.

Nope, sorry.

var player1 = [[7,5],[6,8],[6,9],[1,1],[9,4],[2,2],[6,6],[10,5],[6,4],[4,5],[10,3],[3,1],[10,9],[8,3],[3,8]]
var player2 = [[8,10],[9,6]]
Expected: {"player1":[[6,9],[1,1],[9,4],[2,2],[6,6],[10,5],[6,4],[4,5],[10,3],[3,1],[10,9],[8,3],[3,8]],"player2":[]},
instead got: {"player1":[[6,9],[1,1],[9,4],[2,2],[6,6],[10,5],[6,4],[4,5],[10,3],[3,1],[10,9],[8,3],[3,8]],"player2":[[8,10]]}

am I missing something? player2's [8,10] should survive right?

youre expected to optimize your code so that all the tests pass.

I have two versions that dont pass so I'm trying to improve them

issue or not, the wording about where e and f come from is confusing.

LMFAO WELL DONE

ES6 would be slower cause it needs to go through Babel first. So no.

to pass the performance test am I restricted to ES6 ?

hahaha thanks!!

im guessing this solution was made before the test inputs were changed from array to string

oh my god why didnt I do this
