Question

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

Answer 1

package main

import (
	"fmt"
)

func addOddDigits(n, secondN int) int {
	multiply := 1
	odd := 0

	for n != 0 {
		if n%2 != 0 {
			odd += (n % 10) * multiply
			multiply *= 10
		}

		n /= 10
	}

	return secondN*multiply + odd
}

func main() {
	n := 12734
	secondN := 100

	fmt.Println(addOddDigits(n, secondN))
}
