That statement is inside the for loop that builds the f_curr dict. One
state gets calculated on each iteration. The first time it prints, one
state has been added. The second time it prints, two states have been
added. You only have two states, so at that point the loop is done.
The next time it prints, it's on the next iteration of the outer (i,
x_i) loop and it's building a new f_curr dict. So then you see it
adding one state and then the second state to the new dict. And so on
and so forth until the outer loop completes.
