2.题目代码:

class Solution {
public:
    //水平反转函数
    void replace_photo(vector<int>& array){
        for(int i = 0;i < array.size();i++){
            if(array[i] == 1){
                array[i] = 0;
            }else{
                array[i] = 1;
            }
        }
    }
    vector<vector<int>> flipAndInvertImage(vector<vector<int>>& image) {
        //先进行水平翻转
        for(int i = 0;i < image.size();i++){
            reverse(image[i].begin(),image[i].end());
        }
        //再进行水品反转
        for(int i = 0;i < image.size();i++){
            replace_photo(image[i]);
        }
        return image;
    }
};
