struct TreeNode

{

int val;

TreeNode *left;

TreeNode *right;

};

int visit(TreeNode *root, int &result)

{

if (root == NULL)

{

return 0;

}

int sum = root->val;    
if (root->left != NULL || root->right != NULL)    
{    
    int left = visit(root->left, result);    
    int right = visit(root->right, result);    
    sum += left + right;    

    result = max(sum, result);    
}    

return sum;    

}

int maxSum(TreeNode *root)

{

int result = INT_MIN;

visit(root, result);

return result;    

}
