For 循环迭代字符串切片不起作用

我编写了这段代码，它将小写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，它对短语中的最后一个词没有做任何事情。

如果我用“敏捷的棕色狐狸跳过了懒狗”这句话 我得到“ethay uickqay ownbray oxfay umpedjay overay ethay azylay 狗”

这里一切都是对的，除了最后一个词！为什么它不起作用？ 如果我使用“hello world”作为我的短语，也会发生同样的事情。

包bufio

func (*Reader) 读取字符串

func (b *Reader) ReadString(delim byte) (string, error)

ReadString 读取直到输入中第一次出现 delim， 返回一个包含以下数据的字符串 分隔符。如果 ReadString 在查找之前遇到错误 分隔符，返回出错前读取的数据以及出错后的数据 本身（通常是 io.EOF）。 ReadString 返回 err != nil 当且仅当 返回的数据不以 delim 结尾。

返回一个包含以下数据的字符串 分隔符。

去掉任何尾随的换行符："\n" or "\r\n"。要快速修复，请编写：

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, " "))
}

Output:

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