Answer:
B.O(n).
Explanation:
If the graph is represented by adjacency matrix then we can find all the neighbors of a given vertex in O(n) time because each row in adjacency matrix consists the track of the neighbors.If the other vertex is a neighbor then it contains 1 in adjacency matrix if not it contains 0.So we have to iterate over that row of the vertex to find the neighbors.
B because it uses the suns power to make electricity which doesn't do anything bad to the atmosphere.
it also goes with others but i am not so sure
Explanation:
using random assignment keeps the study from becoming biased or untestable. it gives the results validity.
Pattern recognition is used for similarities between concepts or problems in an algorithm.
What is meant by pattern recognition?
Pattern recognition is a data analysis method that uses machine learning algorithms to automatically recognize patterns and regularities in data. This data can be anything from text and images to sounds or other definable qualities. Pattern recognition systems can recognize familiar patterns quickly and accurately.
An example of pattern recognition is classification, which attempts to assign each input value to one of a given set of classes (for example, determine whether a given email is "spam" or "non-spam").
Therefore, Pattern recognition is used.
