Big-O notation is a way to describe a function that represents the n amount of times a program/function needs to be executed.
(I'm assuming that := is a typo and you mean just =, by the way)
In your case, you have two loops, nested within each other, and both loop to n (inclusive, meaning, that you loop for when i or j is equal to n), and both loops iterate by 1 each loop.
This means that both loops will therefore execute an n amount of times. Now, if the loops were NOT nested, our big-O would be O(2n), because 2 loops would run an n amount of times.
HOWEVER, since the j-loop is nested within i-loop, the j-loop executes every time the i-loop <span>ITERATES.
</span>
As previously mentioned, for every i-loop, there would be an n amount of executions. So if the i-loop is called an n amount of times by the j loop (which executes n times), the big-O notation would be O(n*n), or O(n^2).
(tl;dr) In basic, it is O(n^2) because the loops are nested, meaning that the i-loop would be called n times, and for each iteration, it would call the j-loop n times, resulting in n*n runs.
A way to verify this is to write and test program the above. I sometimes find it easier to wrap my head around concepts after testing them myself.
Answer:
Absolutely yes.
Explanation:
IoT is an acronym for Internet of Things. This is a system of network devices connected together in order to transmit data over the internet. And since communication of these devices is over the internet, there's a need for some protocols for control and moderation. Hence, the need for IoT governance frameworks.
Some of the aspects that should be governed by these frameworks are;
i. Data confidentiality:
Data such as Social Security Numbers, Bank Verification Numbers and Credit card details, that are being transmitted in an IoT system should be assured of protection from unwanted usage or access.
ii. Data integrity:
These data should also be assured of consistency and accuracy over a long period of time.
iii. Accountability:
When there is a breach or some sort of mishappening, there has to be a body that would be held accountable.
