so get the thing, in this case an array at the ith index, and then since we know it is an array, just get the 0th index

in other words to match our example

1. Get the array at the ith spot
2. and then get the first element of that array

I realize this is a year later but i figured i could still answer.

finally! a piece of code i can understand!

what does this line mean stops.get(i)[0]; ?

Thank you.
