问有没有办法在Kotlin的list中合并不同(但相似)对象的值？

EN

fun main() {
    val objects = listOf(
            SomeObject(1, 1, listOf("a")),
            SomeObject(1, 1, listOf("b")),
            SomeObject(1, 2, listOf("c")))


    // group all objects by number and othernumber (both have to match)
    val grouping = objects.groupBy { Pair(it.number, it.otherNumber) }

    // consolidate a grouping onto a new object, so
    // [Pair(1,1), List(SomeObject(1,1,["a","b"]), SomeObject(1,1,["c","d"])) ]
    // [Pair(2,1), List(SomeObject(2,1,["e","f"]), SomeObject(2,1,["g","h"])) ]
    // becomes
    // List(SomeObject(1,1,["a","b", "c", "d"]), SomeObject(2,1,["e","f", "g", "h"]))
    val consolidated = grouping.values.map {
        objectsWithSameNumber ->
        SomeObject(objectsWithSameNumber[0].number,
                   objectsWithSameNumber[0].otherNumber,
                   objectsWithSameNumber.flatMap { it.list })
    }

    /*
    1 1: [a, b]
    1 2: [c]
     */
    for (result in consolidated) {
        println(result)
    }
}

class SomeObject(
        val number: Int,
        val otherNumber: Int,
        val list: List<String>
){
    override fun toString(): String {
        return "$number $otherNumber: $list"
    }
}
