How to check whether a number is Disarium or not
This is the second solution to check the number for Disarium. This solution contains the core logic to evaluate the sum of powers of all digits in descending order of the length of number. The Disarium number is say for a given number 351, evaluate the powers from the left side as power (3 *…

How to check whether a number is Armstrong number or not
This is the first solution to check the number for Armstrong. This solution uses String class, and a couple of Character functions to evaluate the sum of the cubes of each digit in a given number. The Armstrong number is say for a given number 153, evaluate the powers of cubes from any side as…
