153. Find Minimum in Rotated Sorted Array

1. 如果中間的值比最右邊的大，那代表最小值在右區間
2. 如果中間的值比最右邊的小，那代表最小值在左區間

class Solution:
    def findMin(self, nums: List[int]) -> int:
        left = 0
        right = len(nums) - 1

        while left < right:
            mid = left + (right - left ) // 2
            if nums[mid] > nums[right]:
                left = mid + 1
            else:
                right = mid
        return nums[left]
