This is a java program with a class called Sum1.
Explanation:
While loop is used to add 10 number.
import java.util.Scanner;
public class Sum 1
{
public static void main(String args[])
{
int number, count, sum = 0;
Scanner s = new Scanner(System.in);
System.out.print("Enter the number:");
number = s.nextInt();
while(number > 0)
{
count = number % 10;
sum = sum + n;
number = number / 10;
}
System.out.println("Sum of Digits:"+sum);
}
}
Answer:
Explanation:
Duplicate tuples are not allowed in a relation because the specifications of the constraints of the regional integrity are violated, especially the main constraint that states that there can be no identical values for the attributes of two tuples at any database relation state.
Also, duplicate tuples are not allowed in a relation due to the fact that they lead to redundancy of the data base which in turn, slowing down the speed of the database when data processing such as inserting, querying, updating, deleting, etc are being performed.
Answer:
b) The elevator prioritizes the requests that are on the way where it’s going, but also based on a first come first served principle.
Explanation:
Elevator routing often looks complex, as the elevator has to decide whether to go to the person who has waited the longest or the one who is closest? There are also issues of how long should the rider spend.
A simple algorithm can be designed where the elevator prioritizes the requests that are on the way where it’s going, but also based on a first come first served principle. Once it exhausts the request in its current direction, it then switches directions if there are requests in that direction. This way the elevator is able to tackle the complex issue based on the simple algorithm.
