Question

b) Input an integer number (num) and print the sum of only those digits of the number which are multiples of 2 or3.Sample input: num=43961 Sample output : sum = 4 + 3 +9 +6 = 22

Answer 1

Answer:

it's cool and the playlist on the link

Answer 2

here the

input: num=43961

output : sum = 4 + 3 +9 +6 = 22

Explanation:

public class abc

{

  public int Sum(int A, int B) {

      int sum = 0;

      for (int i = A; i <= B; i++) {

          if (i % 2 == 0)

              sum += i;

      }

      return sum;

  }

   

  public double Sum(double N) {

      double p = 1.0;

      for (double i = 1.0; i <= N; i += 0.2)

          p *= i;  

      return p;

  }

   

  public int Sum(int N) {

      int sum = 0;

      while (N != 0) {

          int d = N % 10;

          if (d % 2 != 0)

              sum += d;

          N /= 10;

      }

      return sum;

  }

   

  public static void main(String args[]) {

      abc obj = new abc();

       

      int evenSum = obj.Sum(4, 16);

      System.out.println("Even sum from 4 to 16 = " + evenSum);

       

      double seriesProduct = obj.Sum(2.0);

      System.out.println("Series Product = " + seriesProduct);

       

      int oddDigitSum = obj.Sum(43961);

      System.out.println("Odd Digits Sum = " + oddDigitSum);

  }

}
