Question: Now perform the inverse FFT on the sequence ( 0 , 1 , 4 , 0 ) , also using the recursive al - gorithm.

Now perform the inverse FFT on the sequence (0,1,4,0), also using the recursive al-
gorithm. Recall that the inverse FFT is the same as the forward FFT, but using \omega
1
instead of \omega , and with an extra multiplication by 41
for normalization.
