如何在scala中交换列表中的随机索引？

import scala.util.Random

def swapElements[T](list: List[T], index1: Int, index2: Int): List[T] = {
  list.updated(index1, list(index2)).updated(index2, list(index1))
}

val random = new Random()
val index1 = random.nextInt(list.length)
val index2 = random.nextInt(list.length)

val swappedList = swapElements(list, index1, index2)

import scala.util.Random

def swapElements[T](list: List[T], index1: Int, index2: Int): List[T] = {
  list.updated(index1, list(index2)).updated(index2, list(index1))
}

val list = List(1, 2, 3, 4, 5)
val random = new Random()
val index1 = random.nextInt(list.length)
val index2 = random.nextInt(list.length)
val swappedList = swapElements(list, index1, index2)

println("原始列表：" + list)
println("随机索引：" + index1 + " 和 " + index2)
println("交换后的列表：" + swappedList)
