Narcissistic numbers P29054
In this exercice, we say that a natural number n with k digits is narcissistic, when n is equal to the sum of the k-th power of its digits. For example, 153 and 1634 are narcissistic numbers, as 153 = 13+53+33 and 1634 = 14 + 64 + 34 + 54.
A sequence of natural numbers is insufferably narcissistic when all the elements in the sequence are narcissistic numbers.
Write a program which, given a non-empty sequence of natural numbers, indicates whether it is insufferably narcissitic or not.
Your program must include, implement and use a function
indicating whether a natural n is narcissistic or not.
Input
The input is formed by a non-empty sequence of natural numbers.
Output
The program has to indicate whether the sequence is insufferably narcissitic.
Follow the format described in the examples. Your code should follow the style rules and include the appropriate comments.
