This gist contains the JavaScript solution for the quiz component of the DuoThan 4.0 competition. The code efficiently identifies all Armstrong numbers within the range of 0 to 100,000 using a systematic algorithm. It utilizes functions to check if a number is an Armstrong number and to find all Armstrong numbers within the specified range.

armstrong_numbers_finder.js

// Function to check if a number is an Armstrong number
function isArmstrong(number) {
    // Convert the number to a string to determine its length
    let numStr = String(number);
    let numDigits = numStr.length;
    
    // Calculate the sum of the digits raised to the power of the number of digits
    let sumOfDigits = numStr.split('').reduce((sum, digit) => sum + Math.pow(parseInt(digit), numDigits), 0);
    
    // Check if the sum is equal to the original number
    return sumOfDigits === number;
}

// Function to find Armstrong numbers within the given range
function findArmstrongNumbers() {
    let armstrongNumbers = [];
    for (let num = 0; num <= 100000; num++) {
        if (isArmstrong(num)) {
            armstrongNumbers.push(num);
        }
    }
    return armstrongNumbers;
}

// Print the Armstrong numbers within the range
console.log("Armstrong numbers within the range of 0 to 100,000:");
console.log(findArmstrongNumbers());
