go学习 - 字符串翻转
go学习 - 字符串翻转
代码如下,比较low,但能实现:
package go_test_test
import (
"fmt"
"testing"
)
/**
* Created by Goland
* User: wkk alisleepy@hotmail.com
* Time: 2022/8/5 - 00:21
* Desc: <翻转字符串>
*/
func TestReverseStr(t *testing.T) {
var str, newStr = "abcde", ""
fmt.Println("origin str:", str)
newStr = reverse(str)
fmt.Println("new str:", newStr)
}
// 翻转字符串
// 字符串翻转,先将字符存放在byte切片中,再将byte切片强制类型转换为string
// 字符串本身值不可变,但是可以取值后存放在其他切片中,再将其他切片强制类型转换
func reverse(str string) string {
length := len(str)
if length == 0 {
return ""
}
// 声明切片
var result []byte
for i := 0; i < length; i++ {
result = append(result, str[length-i-1])
}
return string(result)
}
