 * You'll need three keys in order to unlock the
 * Algorithm: the red key, the green key, and the
 * blue key. Unfortunately, all three of them are
 * behind human-proof barriers.
 *
 * The plan is simple: reprogram the maintenance
 * robots to grab the key and bring it through
 * the barrier to us.
 *
 * Let's try it on the red key first.
