Armstrong Number API

Welcome to the Armstrong Number API! This simple Flask-based API allows you to check if a given number is an Armstrong number.

Overview

An Armstrong number (also known as a narcissistic number) is a number that is equal to the sum of its own digits raised to the power of the number of digits. For example, 153 is an Armstrong number because (1^3 + 5^3 + 3^3 = 153).
