## On the Subject of Double Listening

"I don't know the difference, is that arcade or casino?" "Yes."

The module features a play button, a black, square submit button, and five single-bit displays along the bottom. Pressing the play button will play two sounds from the classic Listening module at the same time. The play button has a cooldown period of 3 seconds. Use the original Listening manual to obtain two five-character codes, each corresponding to one of the sounds.

Using the first row from Table A which applies, convert each character in each obtained code to a binary digit.
Perform a bitwise XOR^{*} operation on the two five-digit binary codes and submit the result using the
displays at the bottom of the module.

### Table A

Condition | Symbol | |||
---|---|---|---|---|

# | $ | & | * | |

If the bomb has at least 3 batteries and at least one of the sounds was Beach or Waterfall | 0 | 0 | 1 | 1 |

Otherwise, if the bomb has an empty port plate | 0 | 1 | 0 | 1 |

Otherwise, if the last digit of the bomb's serial number is odd | 1 | 0 | 1 | 0 |

Otherwise | 1 | 1 | 0 | 0 |

NB: Some sounds have had their volume adjusted to prevent them from downing others out.

^{*}To perform a bitwise XOR operation, consider the digits of the two binary codes one position at a time.
The result for each position is a 1 if the digits in the two codes at that position are both different. Otherwise, the
result for that position is a 0.
