  def removeSubarray(array: Array[Int], startIndex: Int, endIndex: Int): Array[Int] = {
    array.slice(0, startIndex) ++ array.slice(endIndex + 1, array.length)

  def main(args: Array[String]): Unit = {
    val array = Array(1, 2, 3, 4, 5, 6, 7, 8)
    val startIndex = 2
    val endIndex = 4

    val subarray = removeSubarray(array, startIndex, endIndex)
