Give the output of the following program segment. How many times is the loop executed?

for(x=10; x>20;x++)

System.out.println(x);

System.out.println(x*2);

To execute a loop 5 times, which of the following is correct?

Define a class to accept a number and check whether it is an FDS Number or not. A number is called an FDS Number if the sum of the factorials of its digits equals the number itself.

Example 1:

Input: 145
Output: FDS Number [1! + 4! + 5! = 1 + 24 + 120 = 145]

Example 2:

Input: 123
Output: Not an FDS Number [1! + 2! + 3! = 1 + 2 + 6 ≠ 123]

import java.util.Scanner;

class KboatFDSNum {
    
    static int fact(int d) {
        int f = 1;
        _______(1)_________ {
            _______(2)_________
        }
        _______(3)_________
    }

    public static void main(String args[]) {
        Scanner in = new Scanner(System.in);

        System.out.print("Enter a number: ");
        int num = in.nextInt();

        int t = num, sum = 0;
        
        _______(4)_________ {
            _______(5)_________
            _______(6)_________
            _______(7)_________
        }
        
        _______(8)_________ {
            _______(9)_________
        } else {
            _______(10)_________
        }
    }
}

Rewrite the following do while program segment using for:

x = 10; y = 20;
do
{
    x++;
    y++;
} while (x<=20);
System.out.println(x * y );
