## Goal

After solving Binary neural network - Part 1, you should now know how to build a simple neural network. The training wheels are off.

** Create a single neural network, with 8 inputs and 8 outputs, that is able to solve all of the provided tests.

Note that it is likely possible to solve them in some other way. You are encouraged to try using a neural network.

Things you might want to experiment with:

- Number of hidden layers
- Number of nodes in the hidden layers
- Number of training iterations
- Learning rate

While the algorithm used to generate the data is the same for both the Tests and the Validators, the data is very different between the two, so it is entirely possible to come up with a solution that can solve all Tests, but not all Validators, or vice-versa. If this happens, I recommend playing around with the above parameters some more until you get it. It's definitely possible.
Input
Line 1: Two space-separated integers: tests and trainingSets
Next tests lines: The testInputs as an 8-digit binary number
Next trainingSets lines: Two 8-digit binary numbers. The first contains the trainingInputs, and the second contains the expectedOutputs for that set of inputs.
Output
tests lines: The output for the associated testInputs. An 8-digit binary number on each line.
