 Logic for  Armstrong   number :)  Armstrong Number An  Armstrong  number is a positive m-digit number that is equal to the sum of the m th  powers of their digits. It is also known as  pluperfect , or  Plus Perfect , or  Narcissistic  number. It is an OEIS sequence  A005188 . Let’s understand it through an example. Armstrong Number Example 1:  1 1  =  1 2:  2 1  =  2 3:  3 1  =  3 153:  1 3  + 5 3  + 3 3  = 1 + 125+ 27 =  153 125:  1 3  + 2 3  + 5 3  = 1 + 8 + 125 =  134 (Not an Armstrong Number) 1634:  1 4  + 6 4  + 3 4  + 4 4  = 1 + 1296 + 81 + 256 =  1643 //Armstrong number list:0,1,153,370,371,407,1634 //Eg 153 rest to 3(Total number of digit ) each digit if addition come original number. package javaPrograms; import java.util.Scanner; public class ArmstrongNumber { public static vo...
