Golang 编写一个求int slice([] int)的最大值最小值的函数

package main
 
import "fmt"
 
func max(l []int) (max int) {
	max = l[0]
	for _, v := range l {
		if v > max {
			max = v
		}
	}
	return
}
 
func min(l []int) (min int) {
	min = l[0]
	for _, v := range l {
		if v < min {
			min = v
		}
	}
	return
}
 
func main()  {
	l := []int{1, 3, 4}
	the_max := max(l)
	the_min := min(l)
	fmt.Printf("The max is %d\n", the_max)
	fmt.Printf("The min is %d\n", the_min)
}
