golang反转字符串
package main
import "fmt"
func reverse(str string) string {
var result []byte
tmp := []byte(str)
length := len(tmp)
fmt.Println(length)
fmt.Println(len(str))
for i := 0; i < length; i++ {
result = append(result, tmp[length-i-1])
}
return string(result)
}
func reverse1(str string) string{
var result string
length := len(str)
for i := 0; i < length; i++ {
result = result + fmt.Sprintf("%c", str[length-i-1])
}
return result
}
func main() {
str := "hello world"
//str := "你好" // 对中文不行
ret := reverse(str)
fmt.Println(ret)
ret = reverse1(str)
fmt.Println(ret)
fmt.Println(str)
}
