题目:
Suppose an array sorted in ascending order is rotated at some pivot unknown to you beforehand.
(i.e., [0,1,2,4,5,6,7] might become [4,5,6,7,0,1,2]).
Find the minimum element.
You may assume no duplicate exists in the array.
Example 1:
Input: [3,4,5,1,2] Output: 1
Example 2:
Input: [4,5,6,7,0,1,2] Output: 0
代码:
class Solution {
public:int findMin(vector<int>& nums) {if(nums.size() == 1)return nums[0];if(nums[0] < nums[nums.size() - 1])return nums[0];int res;for(int i = 0; i<nums.size() - 1; i++){if(nums[i] > nums[i + 1]){res = nums[i + 1];break;}}return res;}
};
