Exercism - Acronym(with.Kotlin)

[문제]

Convert a phrase to its acronym.

Techies love their TLA (Three Letter Acronyms)!

Help generate some jargon by writing a program that converts a long name like Portable Network Graphics to its acronym (PNG).

 

[Solution1]

object Acronym {

    fun generate(phrase : String) : String{

        val strList = phrase.replace("-", " ").split(" ").filter { it.isNotEmpty() }
        
        val expected = CharArray(strList.size)

        strList.mapIndexed { index, s ->
            expected[index] = s.first()
        }

        return expected.joinToString("").toUpperCase()
    }

}

생각이 나는 대로 풀어서 작성하였습니다.

 

[Solution2]

object Acronym {

    fun generate(phrase : String) : String
            = phrase.replace("-", " ")
            .split(" ")
            .filter { it.isNotEmpty() }
            .map { it.first() }
            .joinToString("")
            .toUpperCase()
}

풀어서 작성한것을 정리한 코드입니다.
