Badulla Badu Numbers-------- [extra Quality]

One of the most striking features of Badulla Badu Numbers is their ability to retain their numerical value when their digits are reversed and multiplied by 2. For instance, the number 12, when reversed, becomes 21, and multiplying it by 2 yields 42, which is not equal to 12. However, certain numbers, such as 0, 1, and 2, do exhibit this property.

A number that reads the same forward and backward after a single iterative process of reversal and addition (similar to a Lychrel number candidate, but terminating in exactly one step). Badulla Badu Numbers--------

A (BBN) is a positive integer ( N ) such that when its digits are reversed to form ( N' ), the sum ( N + N' ) is a palindrome, and the product ( N \times N' ) contains no repeated digits in its decimal expansion. A number that reads the same forward and
