你将 不能直接访问该山脉数组,必须通过 MountainArray 接口来获取数据: MountainArray.get(k)- 会返回数组中索引为k 的元素(下标从 0 开始) MountainArray.length()- 会返回该数组的长度 注意: 对MountainArray.get 发起超过 100 次调用的提交将被视为错误答案。此外,任何试图规避判题系统的解决方案都将会导致...

Can you solve it in O(1) space? 分析 题目的意思是:找出一个数组中的mountain array。 大致思路是把每一个位置当成起点,然后先找up上升趋势的值,然后找下降趋势的值,这样就能找到一个mountain array,我们更新res来找到所有mountain array中最长的array的长度。
class Solution: def peakIndexInMountainArray(self, arr: List[int]) -> int: low, high = 1, len(arr) - 2 while low <= high: mid = low + (high - low) // 2 if arr[mid] > arr[mid - 1] and arr[mid] > arr[mid + 1]: return mid elif arr[mid] < arr[mid + 1]: low...
