对leetcode的scala时间限制问题

Question

leetcode上的Scala代码总是得到一个“编译超时”＆＃39;错误。不知道如何处理它。甚至有时幸运地编译。提交结果仍然超过了时间限制＆＃39;。这不是因为我的答案很耗时，而是在最简单的测试用例上失败了。 问题是＆＃39; 135 Candy＆＃39; 这是我的代码。

object Solution {
import scala.annotation.tailrec
def candy(ratings: Array[Int]): Int = {
  candyLoop(ratings.toSeq, -1, 0,0, 0, 0)
}
@tailrec
def candyLoop(remains: Seq[Int],
            tailValue: Int,
            peekCandy:Int,
            tailCandy: Int,
            totalCandy: Int,
            toPeek: Int

           ): Int = {
if (remains.isEmpty) {
  totalCandy
} else {
        //println(s"$tailValue : $tailCandy : $totalCandy : $toPeek")
  val nextVal = remains.head
  if (nextVal > tailValue) {


    candyLoop(remains.tail,
              nextVal,
              tailCandy + 1,
              tailCandy + 1,
              totalCandy + tailCandy + 1,
              0)
  } else if (tailCandy > 1) {
    candyLoop(remains.tail, nextVal,peekCandy, 1, totalCandy + 1, toPeek + 1)
  } else {
    val boost = if(peekCandy > toPeek + 1) toPeek else toPeek + 1
    candyLoop(remains.tail, nextVal, peekCandy,1, totalCandy + boost + 1, toPeek + 1)
  }
}
}
}
