Kotlin Kata - Are We Alternate
Create a function isAlt() that accepts a string as an argument and validates whether the vowels (a, e, i, o, u) and consonants are in alternate order.
isAlt("amazon")
// true
isAlt("apple")
// false
isAlt("banana")
// true
Arguments consist of only lowercase letters.

用 Kotlin 的 regular expression 來處理
fun isAlt(s: String): Boolean {
return !Regex("""[aeiou]{2}|[^aeiou]{2}""").containsMatchIn(s)
}
