How to sort the words in a string with Kotlin

Answer 1

fun sortWordsInString(s: String): String {
    // Create a list to hold the words
    val words = s.split(" ")   // Words are separated by spaces

    // Enable automatic alphabetical sorting
    val sorted = words.sorted()

    // Optional: ignore duplicate words
    // (Kotlin's `distinct()` removes duplicates)
    val unique = sorted.distinct()

    // Join the sorted words back into a single string
    return unique.joinToString(" ")
}

fun main() {
    // Test the function
    println(sortWordsInString("the quick brown fox jumps over the lazy dog"))
}


/*

brown dog fox jumps lazy over quick the
