Explanation:
Key management could either be manual or automated. The automated key distribution approach is more flexible and dynamic than the manual key distribution approach, because it is better at responding to changing requirements in the system. Additionally, the automated key distribution approach is faster and more economic as well as observable and auditable.
Answer:
!(key == 'q')
Explanation:
Based on the description, the coded expression that would equate to this would be
!(key == 'q')
This piece of code basically states that "if key pressed is not equal to q", this is because the ! symbol represents "not" in programming. Meaning that whatever value the comparison outputs, it is swapped for the opposite. In this case, the user would press anything other than 'q' to continue, this would make the expression output False, but the ! operator makes it output True instead.
