flatMap 이럴때 쓰더라구요

fun testStream1() {
            val pythagoreanTripleList: List<Array<Double>> = IntStream.rangeClosed(1, 100)
                .boxed()
                .flatMap { a ->
                    IntStream.range(a, 100)
                        .boxed()
                        .map { b: Int ->
                            arrayOf(a.toDouble(), b.toDouble(), sqrt(a.toDouble() * a + b * b))
                        }
                        .filter { it[2] % 1.0 == 0.0 }
                }
                .collect(toList())
                .orEmpty()
