What is strong number in java script?

Answer 1

In JavaScript, a "strong number" (or "Armstrong number") for a given number of digits 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 is a strong number because it has three digits, and (1^3 + 5^3 + 3^3 = 153). To determine if a number is a strong number, you can convert it to a string to access each digit, calculate the sum of the digits raised to the appropriate power, and then compare it to the original number.
