go - 如何在 Go 中使用排序包反转字符串 slice ？

Question

strArr := []string{"one", "two", "three"}
// expected Result : ["three", "two, "one"]

我想使用 sort package 来做到这一点

Comment: Something like this in JavaScript : strArr.reverse(). – Jackal

JavaScript: Array.prototype.reverse()

The reverse() method reverses an array in place. The first array element becomes the last, and the last array element becomes the first.

例如，

package main

import (
    "fmt"
)

func reverse(s []string) {
    for i, j := 0, len(s)-1; i < j; i, j = i+1, j-1 {
        s[i], s[j] = s[j], s[i]
    }
}

func main() {
    strArr := []string{"one", "two", "three"}
    fmt.Println(strArr)
    reverse(strArr)
    fmt.Println(strArr)
    reverse(strArr)
    fmt.Println(strArr)
}

输出:

[one two three]
[three two one]
[one two three]
