CF1217F Forced Online Queries Problem

You are given an undirected graph with $ n $ vertices numbered from $ 1 $ to $ n $ . Initially there are no edges. You are asked to perform some queries on the graph. Let $ last $ be the answer to the latest query of the second type, it is set to $ 0 $ before the first such query. Then the queries are the following: - $ 1~x~y $ ( $ 1 \le x, y \le n $ , $ x \ne y $ ) — add an undirected edge between the vertices $ (x + last - 1)~mod~n + 1 $ and $ (y + last - 1)~mod~n + 1 $ if it doesn't exist yet, otherwise remove it; - $ 2~x~y $ ( $ 1 \le x, y \le n $ , $ x \ne y $ ) — check if there exists a path between the vertices $ (x + last - 1)~mod~n + 1 $ and $ (y + last - 1)~mod~n + 1 $ , which goes only through currently existing edges, and set $ last $ to $ 1 $ if so and $ 0 $ otherwise. Good luck!

The first line contains two integer numbers $ n $ and $ m $ ( $ 2 \le n, m \le 2 \cdot 10^5 $ ) — the number of vertices and the number of queries, respectively. Each of the following $ m $ lines contains a query of one of two aforementioned types. It is guaranteed that there is at least one query of the second type.

Print a string, consisting of characters '0' and '1'. The $ i $ -th character should be the answer to the $ i $ -th query of the second type. Therefore the length of the string should be equal to the number of queries of the second type.

The converted queries in the first example are: - 1 1 2 - 1 1 3 - 2 3 2 - 1 3 5 - 2 4 5 - 1 2 4 - 2 3 4 - 1 2 4 - 2 5 4 The converted queries in the second example are: - 1 1 2 - 1 2 3 - 1 3 1 - 2 1 3 - 1 1 3 - 2 3 1 - 1 2 3 - 2 2 3 - 2 1 2
