An Armstrong number of three digits is a number such that the sum of the cubes of its digits is equal to the number itself. 371 is an Armstrong number since 33 + 73 + 13 = 371. In case of an Armstrong number of 3 digits, the sum of cubes of each digit is equal to the number itself. For example: Given a number x. Write a Java Program to determine whether the given number is Armstrong 's number or not. In this article, we will learn how to check Armstrong Numbers in Java. What is Armstrong 's Number ? In a mathematical number system, the Armstrong number is the number in any given number base, which makes the total of the same number when each of its digits is raised to the power of the total number of digits in the number . In simple words, we can say that a positive integer of n digits ... Given a number x, determine whether given number is Armstrong number or not. An Armstrong number is a number that is equal to the sum of its own digits each raised to the power of the number of digits. For example: 153 = 1³ + 5³ + 3³ = 153 ( Armstrong number ) 120 ≠ 1³ + 2³ + 0³ = 9 (Not an Armstrong number ) Let’s explore different methods to check Armstrong numbers one by one. Mathematical Method (Most Optimal) This is the fastest and most efficient way to check an Armstrong number ...
