Go反转字符串

似乎没什么好办法，string的话也得需要先转换成rune再反转再转成string

package main

import (
        "fmt"
)

func reverseString(s string) string {
    runes := []rune(s)

    for from, to := 0, len(runes)-1; from < to; from, to = from + 1, to - 1 {
        runes[from], runes[to] = runes[to], runes[from] 
    } 

    return string(runes)
}

func main(){
    //testString := "abc"
    testString := ""


    ans := reverseString(testString)

    fmt.Println(ans)
}
