Answer:
Collaborative filtering
Explanation:
This is one out of five on the Recommender system apart from most popular items, Association and Market Basket based Analysis, Content-based analysis, self and hybrid analysis where we use both content-based and collaborative based approach together. And the Recommender system is a very important topic in Data science. For this question, remember that Collaborative filtering focuses on user and various other user's choices which are mathematically alike to concerned users, and which we find with the study of a large data set. Thus, we can predict from our above study that what are going to be likes of concerned users, and at the item level, whether that item will be liked by the concerned user or not. And this is prediction, and we use this approach in Machine learning these days. For this question, and as mentioned in question the requirements, answer is Collaborative filtering.

Answer:
B. The employees contact the labor union arbitrator, who then sends an e-mail to Todd.
Explanation
Todd, 5he manager has just received a grievance filed by his subordinates who are union members because of a dispute.
A grievance can be filed when there is dissatisfaction at work, or anger at policy or something else that is a work related grievance.
The likeliest scenario for escalating their dissatisfaction to their employee would be to present their grievance through their union arbitrator who is charged with protecting the work interests of its union members.
This is necessary because the employer knows the anger of the employees and dialogue can take place.
Answer:
Answer explained below
Explanation:
void bubbleSort(int X[], int Y[], int n)
{
int i, j;
for (i = 0; i < n-1; i++)
// Last i elements are already in place
for (j = 0; j < n-i-1; j++)
if (X[j] > X[j+1])
{
swap(X[j],X[j+1])
swap(Y[j],Y[j+1]);
}
if (X[j] == X[j+1]&&Y[j]<Y[j+1])
{
swap(X[j],X[j+1])
swap(Y[j],Y[j+1]);
}
}
Since the above algorithm contains 2 nested loops over n.
So, it is O(n^2)
