Answer:
The method in Java is as follows:
public static int numUnique(int list[]) {
int unique = 1;
for (int i = 1; i < list.length; i++) {
int j = 0;
for (j = 0; j < i; j++) {
if (list[i] == list[j])
break;
}
if (i == j)
unique++;
}
return unique;
}
Explanation:
This line defines the numUnique method
public static int numUnique(int list[]) {
This initializes the number of unique elements to 1
int unique = 1;
This iterates through the list
for (int i = 1; i < list.length; i++) {
The following iteration checks for unique items
int j = 0;
<em> for (j = 0; j < i; j++) {
</em>
<em> if (list[i] == list[j]) </em><em>If current element is unique, break the iteration</em><em>
</em>
<em> break; </em>
<em> }
</em>
if (i == j)
unique++;
}
This returns the number of unique items in the list
return unique;
}

Web server
Explanation:
A web server's main function is to process, store, and deliver web pages to clients. The Hypertext Transfer Protocol takes care of the communication between the server and the client. If a web server is malfunctioning, any website you try to open on your browser would display a "page not found" error on your screen.
