Answer: Lattice-based, non-discretionary
Explanation: Lattice-based access control is a form of non-discretionary access control in which users are assigned a matrix of authorizations for particular areas of access. Lattice-based access control are usually used to restrict or define the level of authorization granted to a subject which may be an individual, organization or group or the that given to the object which may include applications and computers.It utilizes a non-discretionary approach whereby the defined access is uniformly enforced across all subjects and objects within the confines of an information system.
Answer: This is a python code
def lightyear():
rate=3*100000000 //speed of light
seconds=365*24*60*60 //number of seconds in 1 year
return str((rate*seconds)/1000)+" km" //distance=speed x time
print(lightyear()) //will print value of light hear in kilometers
OUTPUT :
9460800000000.0 km
Explanation:
In the above code, there is a variable rate, which stores the speed of light, i.e. distance traveled by light in 1 second which is in meters. Another variable is seconds, which store the number of seconds in 1 year, which is no of days in 1 year multiplied by the number of hours in a day multiplied by the number of minutes in an hour multiplied by the number of seconds in a minute. Finally, distance is speed multiplied by time, so distance is printed in kilometers and to convert distance in kilometers it is divided by 1000.
Answer:
O(n^2)
Explanation:
The number of elements in the array X is proportional to the algorithm E runs time:
For one element (i=1) -> O(1)
For two elements (i=2) -> O(2)
.
.
.
For n elements (i=n) -> O(n)
If the array has n elements the algorithm D will call the algorithm E n times, so we have a maximum time of n times n, therefore the worst-case running time of D is O(n^2)
I should be skeptical of the credibility of sources that I have during the gathering. Be cautious and make sure that data comes of from trusted specialized sources. Trusted sources can be easily identified for their popularity on certain fields. Determine the purpose of the site and the data it contains.
