int fact;
Console.Write("\n\n");
Console.Write("Check whether a number is Strong Number or not:\n");
Console.Write("-------------------------------------------------");
Console.Write("\n\n");
/* If sum of factorial of digits is equal to original number then it is Strong number */
Console.Write("Input a number to check whether it is Strong number: ");
n = Convert.ToInt32(Console.ReadLine());
n1 = n;
for(j=n;j>0;j=j/10)
{
fact = 1;
for(i=1; i<=j % 10; i++)
{
fact = fact * i;
}
s1 = s1 + fact;
}
if(s1==n1)
{
Console.Write("\n{0} is Strong number.\n\n", n1);
