Question

How to write an algorithm that adds the odd digits of one number to the end of a second number in Kotlin

Answer 1

fun addOddDigits(n: Int, second_n: Int): Int {
    var multiply = 1
    var odd = 0
    var number = n

    while (number != 0) {
        if (number % 2 != 0) {
            odd += (number % 10) * multiply
            multiply *= 10
        }
        
        number /= 10
    }

    return second_n * multiply + odd
}

fun main() {
    val n = 12734
    val second_n = 100
    
    println(addOddDigits(n, second_n))
}
