[LeetCode]Find Minimum in Rotated Sorted Array

題目描述：

Suppose a sorted array 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.

解題方案：

直接貼代碼，因為我沒有太明白題目描述那么多是怎么意思。如果那位大神明白了，請告訴我。輕噴！！！

class Solution {
public:
    int findMin(vector<int> &num) {
        int MinElem = INT_MAX;
        for (size_t i = 0; i <num.size(); ++i) {
            if (num[i] < MinElem) {
                MinElem = num[i];
            }
        }
        return MinElem;
    }
};
