Go语言ReverseVowelsofaString

主要是判断是不是元音字符，没啥难度，记得实际写的时候要去掉魔鬼数字

package mainimport (    "fmt"   )//注意考虑大小写func isVowel(vowel rune) bool {    if vowel == 97 || vowel == 97-32 {        return true     }    if vowel == 101 || vowel == 101-32 {        return true     }    if vowel == 105 || vowel == 105-32 {        return true     }    if vowel == 111 || vowel == 111-32 {        return true     }    if vowel == 117 || vowel == 117-32 {        return true     }    return false}func reverseVowels(s string) string {    runeString := []rune(s)    flag := false    for from, to := 0, len(s)-1; from < to; from, to = from+1, to-1 {        for {            flag = isVowel(runeString[from])            if flag || from >= to{                break               }            from++        }           for {            flag = isVowel(runeString[to])            if flag || from >= to{                break               }            to--        }        runeString[from], runeString[to] = runeString[to], runeString[from]    }    return string(runeString)}func main(){    //ans := reverseVowels("helalo")    //ans := reverseVowels("hll")    //ans := reverseVowels("hello")    ans := reverseVowels("Aa")    fmt.Println(ans)    }
