用golang写一个洗牌算法？

package main

import ( "fmt" "math/rand" "time" )

func shuffle(slice []int) []int { rand.Seed(time.Now().UnixNano())

for i := len(slice) - 1; i > 0; i-- {
	j := rand.Intn(i + 1)
	slice[i], slice[j] = slice[j], slice[i]
}

return slice

}

func main() { slice := []int{1, 2, 3, 4, 5} shuffledSlice := shuffle(slice) fmt.Println(shuffledSlice) }
