    class Solution {
    public:
    int* dfs(TreeNode* root){
    int row[2] = {0,0};
    if(!root){
    return row;
    }
    int* left = dfs(root->left);
    int* right = dfs(root->right);
    row[0] = left[1]+right[1];
    row[1] = max(left[0]+right[0]+root->val, left[1]+right[1]);
    return row;
    }
    int rob(TreeNode* root) {
    return dfs(root)[1];
    }
    };
