Question

SQL：

struct node
    {
        int data;
        node* left;
        node* right;
    };

void order (node* root, map <int, vector <int> >& ans, int level, int k) {
    if (root == NULL) {
        return;
    }

    if (k==0) {
        if (root->left != NULL) {
            ans[level+1].push_back(root->left->data);
            order (root->left, ans, level+1, 1);
        }
        if (root->right != NULL) {
            ans[level+1].push_back(root->right->data);
            order (root->right, ans, level+1, 1);
        }
    }
    else if (k==1) {
        order (root->left, ans, level+1, 0);
        order (root->right, ans, level+1, 0);

        if (root->right != NULL)
            ans[level+1].push_back(root->right->data);
        if (root->left != NULL)
            ans[level+1].push_back(root->left->data);
    }
}

vector<vector<int> > zigzag(node* root){
     map <int, vector <int> > ans;
     vector <vector <int> > zig;

     ans[0].push_back(root->data);

     order(root, ans, 1, 1);

     for (auto it = ans.begin(); it != ans.end(); it++ ) {   //converting map into vector
        zig.push_back(it->second);
     }
     return zig;
 }
