对于字符串切片上的循环迭代，不起作用

Question

我写了这段代码，它应该把小写的英语短语翻译成猪拉丁语。

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, " "))
}

然而，它没有对短语中的最后一个字做任何事情。

如果我用“快棕狐狸跳过懒狗”这句话，我就会得到“ownbray oxfay umpedjay overay ethay azylay狗”。

这里的一切都是对的，除了最后一句话！为什么不动呢？如果我用“你好世界”作为我的短语，也会发生同样的事情。

包装布菲奥 (读者) ReadString 函数(b *读取器) ReadString(delim字节)(字符串，错误) ReadString在输入中读取数据，直到第一次出现delim为止，返回一个字符串，其中包含数据和分隔符。如果ReadString在找到分隔符之前遇到错误，它会返回错误之前读取的数据和错误本身(通常是io.EOF)。ReadString返回err != nil当且仅当返回的数据没有以delim结尾。

返回一个字符串，该字符串包含数据，并包含分隔符。

去掉任何后面的换行符："\n"或"\r\n"。要想快速解决问题，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
