You are given an undirected graph with N vertices and 0 edges. Process Q queries of the following types.

* `0 u v`: Add an edge (u, v).
* `1 u v`: Print 1 if u and v are in the same connected component, 0 otherwise.

Constraints

* 1 \leq N \leq 200,000
* 1 \leq Q \leq 200,000
* 0 \leq u_i, v_i \lt N

Input

Input is given from Standard Input in the following format:


N Q
t_1 u_1 v_1
t_2 u_2 v_2
:
t_Q u_Q v_Q


出力

For each query of the latter type, print the answer.

Example

Input

1 0 1
1 1 2
0 0 2
1 1 3
