RNN

RNN is iterative output:

Input first -> output second,
input second -> output third,
output second last -> output last.

LSTM

LSTM is also iterative output:

Input first -> output second,
input second -> output third,
output second last -> output last.

GRU

GRU is also iterative output:

Input first -> output second,
input second -> output third,
output second last -> output last.
