剑指offer6 旋转数组的最小数字

这题我都简直了.......大水题

#include "iostream"
#include "vector"
using namespace std;

class Solution {
public:
int minNumberInRotateArray(vector<int> rotateArray) {

if(rotateArray.size()==0)
return 0;

int min = 9999999;
for(vector<int>::iterator iter = rotateArray.begin();iter != rotateArray.end();iter++)
{
if(*iter<min)
min = *iter;
}

return min;
}
};

int main()
{
Solution test;
vector<int> num;
num.push_back(3);
num.push_back(4);
num.push_back(5);
num.push_back(1);
num.push_back(2);

int result = test.minNumberInRotateArray(num);
cout<<result<<endl;

return 0;
}
