Armstrong Number
An Armstrong number is a number that reveals a special mathematical balance. It is a number that remains unchanged when each of its digits is raised to the power of the total number of digits and the results are added together. If this sum equals the original number, it is called an Armstrong number.
For example, 153 has three digits:
1³ + 5³ + 3³ = 1 + 125 + 27 = 153
Since the sum equals the original number, 153 is an Armstrong number. These numbers are fascinating because they demonstrate a rare harmony between a number and its individual digits, making them an interesting concept in mathematics and computer programming.
