Output: 1

Input: num = 321
Output: 6

Code:

package main

import (
  "fmt"
)

func digit_sum(num int) int {

  sum := 0

  for i := num; i > 0; i = i / 10 {

    sum = sum + (i % 10)

  }

  return sum

}

func main() {

  sum := digit_sum(13)

  fmt.Println(sum)

  sum = digit_sum(10)

  fmt.Println(sum)

  sum = digit_sum(321)

  fmt.Println(sum)
}
