About two weeks ago, I posted
this about FizzBuzz in ABAP, and solving programming puzzles. It seems it was well received, so here's another one that may or may not be simple to solve.
Narcissistic numbers
In number theory, a narcissistic number is a number where the sum of each of its digits raised to the power of the total number of digits equals the number itself. This is the case for instance for the number 153. It has 3 digits, so when each digit is raised to the power 3, then the sum equals 153.
1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153
(Narcissistic numbers are also known as Armstrong numbers or plus perfect numbers.)
The suggested task here is to implement a program that lists all narcissistic numbers with 5 or less digits, i.e. between 0 and 99999.
These are, for reference 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 153, 370, 371, 407, 1634, 8208, 9474, 54748, 92727 and 93084
I have made some examples solution and posted in
this ABAP puzzle repository.
Have fun, and enjoy your process!
