Go语言实现选择法排序

package main
import "fmt"
func select_sort(a []int) {
    len := len(a)
    for i:=0; i < len-1; i++ {
        k := i
        j:= i + 1

        for ; j < len; j++ {
            if a[j] < a[k] { k = j }
        }
        if k != i {
            a[i], a[k] = a[k], a[i] 
        }
    }
}
func print_array(a []int) {
    for i := 0; i < len(a) - 1; i++ {
        fmt.Printf("%d, ", a[i])
    }
    fmt.Print(a[len(a)-1])
}
func main() {
    a := []int{1, 8, 5, 9, 4, 3, 6, 6}
    print_array(a)
    fmt.Printf("\n")
    select_sort(a)
    print_array(a)
}
