eMahtab / Armstrong.java
Created November 19, 2015 06:22
Java Program for calculating Armstrong number. 153 is an armstrong number as 1^(number of digits)+5^(number of digits)+3^(number of digits)=153. Similarly 371 is an armstrong number 3^(number of digits)+7^(number of digits)+1^(number of digits)=371.
