/* Parity Benchmark Data Set Generator
v1.0
Matt White (mwhite+@cmu.edu)
9/19/93
QUESTIONS/COMMENTS: neural-bench@cs.cmu.edu
Usage: a.out <# of inputs>
# of inputs defaults to 2, or XOR.
Care should be taken not to input a number greater than the number
of bits, usually 32, of the machine being used, minus one. Thus,
for most computers, the maximum input is 31.
Description
~~~~~~~~~~~
This program generates parity benchmark data in the CMU Neural
Network Benchmark format.
