Accessing elements inside Array elements in scala

Question

In scala, I know you can access the n'th element in an Array with Array(n), for example z(1) = (3, 4) for the array z:

z: Array[(Int, Int)] = Array((1,2), (3,4), (6,7), (8,9))

But how do I acsess the first element in the second element (which would be 3)?

(3, 4) is of type Tuple2.

You can access its first element via:

val first = z(1)._1

or:

val (first, _) = z(1)
