The second one uses mutation, the first one doesn't.

im just trying to understand what the question wants as far as what is the difference between modifying the array and modifying just the Posn's in the array

I'm sorry, but these explanations make no sense. Does number 1 want
you to just modify the array without bothering to make new Posns? And
does number 2 want you to actually put "new Posn" in for each
position? It would really help to have the purpose of each outlined in
contrast with each other.

2 has the same posns, modified, in the same array
