对于字符串切片的循环迭代不起作用

我写了这段代码，它将一个小写的英语短语翻译成猪拉丁。

package main

import (
    "fmt"
    "strings"
    "bufio"
    "github.com/stretchr/stew/slice"
    "regexp"
    "os"
)

func main() {
    lst := []string{"sh", "gl", "ch", "ph", "tr", "br", "fr", "bl", "gr", "st", "sl", "cl", "pl", "fl", "th"}
    reader := bufio.NewReader(os.Stdin)
    fmt.Print("Type what you would like translated into pig-latin and press ENTER: ")
    sentenceraw, _ := reader.ReadString('\n')
    sentence := strings.Split(sentenceraw, " ")
    isAlpha := regexp.MustCompile(`^[A-Za-z]+$`).MatchString
    newsentence := make([]string, 0)
    for _, i := range sentence {
        if slice.Contains([]byte{'a', 'e', 'i', 'o', 'u'}, i[0]) {
            newsentence = append(newsentence, strings.Join([]string{string(i), "ay"}, ""))
        } else if slice.Contains(lst, string(i[0])+string(i[1])) {
            newsentence = append(newsentence, strings.Join([]string{string(i[2:]), string(i[:2]), "ay"}, ""))
        } else if !isAlpha(string(i)) {
            newsentence = append(newsentence, strings.Join([]string{string(i)}, ""))
        } else {
            newsentence = append(newsentence, strings.Join([]string{string(i[1:]), string(i[0]), "ay"}, ""))
        }
    }
    fmt.Println(strings.Join(newsentence, " "))
}

但是，它对短语中的最后一个单词没有任何作用。

如果我使用“快速的棕色狐狸跳过懒狗”这句话，我会得到“ ethay uickqayownbray oxfay umpedjay overay ethay
azylay狗”

这里的一切都正确，除了硬道理！为什么不起作用？如果我使用“ hello world”作为短语，也会发生同样的事情。

软件包bufio

func（* Reader）ReadString
func (b *Reader) ReadString(delim byte) (string, error)
ReadString读取直到输入中第一次出现delim为止，并返回一个字符串，其中包含直到定界符（包括定界符）的数据。如果ReadString在找到定界符之前遇到错误，它将返回错误之前读取的数据和错误本身（通常为io.EOF）。当且仅当返回的数据未以delim结尾时，ReadString才返回err！=
nil。

返回一个字符串，该字符串包含直到定界符（包括定界符）的数据。

删除任何结尾的换行符："\n"或"\r\n"。为了快速解决，请写：

sentence := strings.Split(strings.TrimSpace(sentenceraw), " ")

例如，

package main

import (
    "bufio"
    "fmt"
    "os"
    "regexp"
    "strings"

    "github.com/stretchr/stew/slice"
)

func main() {
    lst := []string{"sh", "gl", "ch", "ph", "tr", "br", "fr", "bl", "gr", "st", "sl", "cl", "pl", "fl", "th"}
    reader := bufio.NewReader(os.Stdin)
    fmt.Print("Type what you would like translated into pig-latin and press ENTER: ")
    sentenceraw, _ := reader.ReadString('\n')
    sentence := strings.Split(strings.TrimSpace(sentenceraw), " ")
    isAlpha := regexp.MustCompile(`^[A-Za-z]+$`).MatchString
    newsentence := make([]string, 0)
    for _, i := range sentence {
        if slice.Contains([]byte{'a', 'e', 'i', 'o', 'u'}, i[0]) {
            newsentence = append(newsentence, strings.Join([]string{string(i), "ay"}, ""))
        } else if slice.Contains(lst, string(i[0])+string(i[1])) {
            newsentence = append(newsentence, strings.Join([]string{string(i[2:]), string(i[:2]), "ay"}, ""))
        } else if !isAlpha(string(i)) {
            newsentence = append(newsentence, strings.Join([]string{string(i)}, ""))
        } else {
            newsentence = append(newsentence, strings.Join([]string{string(i[1:]), string(i[0]), "ay"}, ""))
        }
    }
    fmt.Println(strings.Join(newsentence, " "))
}

输出：

Type what you would like translated into pig-latin and press ENTER: hello world
