分析

太简单了，一分钟ac

代码如下：

class Solution {
public:
    int findMaxConsecutiveOnes(vector<int>& nums) {
        if(nums.size() == 0)return 0;
        int max = 0;
        int length = 0;
        for(int i = 0; i != nums.size(); ++i){
            if(nums[i] == 1){
                ++length;
                max = length > max ? length : max;
            }else{
                length = 0;
            }
        }
        return max;
    }
};
