task clarification
According to this task's link to Wolfram MathWorld (TM), a narcissistic number is an N-digit number whose ...
The first narcissistic number is 0 (zero).
According to OEIS (The On-line Encyclopedia of Integer Sequences (R)), the first narcissistic number is 0 (zero).
This would change what numbers are listed when displaying 25 narcissistic numbers.
I would prefer mentioning that narcissistic numbers are non-negative integers. After all, 15.3 is a decimal number.
Also, for those searching for Armstrong numbers, maybe a note saying:
Narcissistic numbers are also known as:
- Armstrong numbers
- perfect digital invariant (Madachy 1979)
- plus perfect numbers (Hardy 1993)
Narcissistic numbers are similar to powerful numbers. Powerful numbers are integers that are equal to some fixed (integer) power of their digits.
The list of narcissistic numbers is finite (89).
