go 字符串反转（倒序）

2024-08-29 15:43:11

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 := "abcdefg12345"

// testString := ""

ans := reverseString(testString)

fmt.Println(ans)

}
