golang如何把数组的最后一项移到第一项？

Question

如题

["a","b","c"] --> ["c","b","a"]

Answer 1

    a := []string{"A","B","C"}
    
    b := append(a[2:],a[0:2]...)

    fmt.Println(a,b)
-> [A B C] [C A B]

Answer 2

package main

import "fmt"

func main() {
    a := [3]string{"a", "b", "c"}
    a[0], a[len(a)-1] = a[len(a)-1], a[0]
    fmt.Println(a)
}
