Bug-out Shelter #4 – Vital Silence

Mission

You understand that it’s no longer just about observing the threat — immediate action is required.
The first step is to verify internally that the shelter remains invisible. Every system — ventilation, energy, communications, water circulation — is capable of generating noise or signals that could be detected from the outside. The slightest leak or anomaly could become the weak link.

You must therefore analyze the shelter’s operational data to detect all suspicious emissions, neutralize the dangerous ones, and preserve the absolute silence that is keeping you alive.

Rules

You have 2 variables at your disposal:

• control: contains the noise threshold to check against.
• equipements: contains the list of equipment to monitor.

Each piece of equipment is represented by 2 pieces of information:

• Its 2-letter code
• Its noise level

You must check each piece of equipment and identify those whose noise level is higher than the control point.
For these, you need to calculate how much to reduce their noise to bring them back to the accepted level.

You must return the codes of the equipment that exceed the control level AND the sum of the reductions applied to these pieces of equipment (separated by an underscore).
