System.out.print("Enter number: ");
int n = in.nextInt();
while (n != 0) {
int d = n % 10;
n /= 10;
int f = 1;
for (int i = 1; i <= d; i++) {
f *= i;
}
System.out.println("Factorial of " + d + " = " + f);
}
}
}Output

Rewrite the following do while program segment using for:
x = 10; y = 20; do { x++; y++; } while (x<=20); System.out.println(x * y );To execute a loop 10 times, which of the following is correct?
- for (int i=11;i<=30;i+=2)
- for (int i=11;i<=30;i+=3)
- for (int i=11;i<20;i++)
- for (int i=11;i<=21;i++)
How many times will the following loop execute?
int a = 5; while (a > 0) { System.out.println(a-- + 2); if (a % 2 == 0) break; }Define a class to accept a number and check whether it is a SUPERSPY number or not. A number is called SUPERSPY if the sum of the digits equals the number of the digits.
Example1:
Input: 1021 output: SUPERSPY number [SUM OF THE DIGITS = 1+0+2+1 = 4, NUMBER OF DIGITS = 4 ]Example2:
Input: 125 output: Not an SUPERSPY number [1+2+5 is not equal to 3]
