ICE self-referential array building, without a loop?

[Alan Fregtman]

Hey guys,

At the risk of looking stupid, I'm wondering if anyone knows a cool
way of procedurally generating an array from a given length that
results in:
#0: 1
#1: 10
#2: 100
#3: 1000
#4: 10000
#5: ...
and so on.

The reason I used the term "self-referential" is because with a
repeat/while loop I can generate easily with an "algorithm"
referencing the previous item in its own array, like so:
10*(#0)=(#1) = 10*1=10
10*(#1)=(#2) = 10*10=100
10*(#2)=(#3) = 10*100=1000
10*(#3)=(#4) = 10*1000=10000
I suppose it could also be called "recursive", somewhat.

Seems to me there must be a simpler way to do this without a loop,
right? Maybe more coffee is the answer...

Any clues appreciated.
Cheers,

Those are powers of 10, so plug an Build Index Array into an Exponent node and ...

Ahhhh! Completely forgot about the Exponent node. Thanks Stephen!
