Scala一个数组的间隔数的索引

def findIndexesWithInterval(arr: Array[Int], value1: Int, value2: Int): (Int, Int) = {
  val index1 = arr.indexOf(value1)
  val index2 = arr.indexOf(value2)

  if (index1 == -1 || index2 == -1) {
    throw new IllegalArgumentException("One or both values not found in the array.")
  }

  // 确保index1小于index2
  val (startIndex, endIndex) = if (index1 < index2) (index1, index2) else (index2, index1)

  (startIndex + 1, endIndex - 1)
}

// 使用示例
val array = Array(1, 2, 3, 4, 5, 6, 7, 8, 9)
val (startIndex, endIndex) = findIndexesWithInterval(array, 3, 7)
println(s"Indexes with interval between 3 and 7: $startIndex to $endIndex")
