  cout << "Enter minimum range: ";

  cout << "Strong numbers in given range are: ";
  for(num=min; num <= max; num++){
      temp = num;
      sum=0;

      while(temp){
           i=1;
           f=1;
           r=temp%10;

           while(i<=r){
             f=f*i;
             i++;
           }
         sum=sum+f;
         temp=temp/10;
      }
       
      if(sum==num)
          cout << num;
