Kotlin Program to Display Armstrong Number Between Two Intervals

Source Code

fun main(args: Array<String>) {
    val low = 999
    val high = 99999

    for (number in low + 1..high - 1) {
        var digits = 0
        var result = 0
        var originalNumber = number

        // number of digits calculation
        while (originalNumber != 0) {
            originalNumber /= 10
            ++digits
        }

        originalNumber = number

        // result contains sum of nth power of its digits
        while (originalNumber != 0) {
            val remainder = originalNumber % 10
            result += Math.pow(remainder.toDouble(), digits.toDouble()).toInt()
            originalNumber /= 10
        }

        if (result == number)
            print("$number ")
    }
}
