Explanation:
Logic
What is an Armstrong number?
- A number is an Armstrong number if the sum of its digits raised to the power of the number of digits equals the number itself.
- For example, 153 = 13 + 53 + 33.
Steps:
- Define a function to check if a number is an Armstrong number.
- Start from n and keep checking numbers until m
- Print each Armstrong number as it is identified.
