Problem: Write a program which manipulates a disjoint set S = {S1, S2, . . . , Sk}.

First of all, the program should read an integer n, then make a disjoint set where each element consists of 0, 1, ... n−1 respectively.

Next, the program should read an integer q and manipulate the set for q queries. There are two kinds of queries for different operations:

* unite(x, y): unites sets that contain x and y, say Sx and Sy, into a new set.
* same(x, y): determine whether x and y are in the same set.

Constraints

* 1 ≤ n ≤ 10000
* 1 ≤ q ≤ 100000
* x ≠ y

Input


n q
com1 x1 y1
com2 x2 y2
...
comq xq yq


In the first line, n and q are given. Then, q queries are given where com represents the type of queries. '0' denotes unite and '1' denotes same operation.

Output

For each same operation, print 1 if x and y are in the same set, otherwise 0, in a line.

Example

Input

5 12
0 1 4
0 2 3
1 1 2
1 3 4
1 1 4
1 3 2
0 1 3
1 2 4
1 3 0
0 0 4
1 0 2
1 3 0


Output

0
0
1
1
1
0
1
1

Solution (in CPP):

Solution:
#include <iostream>
using namespace std;
int P[10010];
int root(int a) {
 if (P[a] == a) return a;
 return (P[a] = root(P[a]));
}
bool is_same_set(int a, int b) {
 return root(a) == root(b);
}
void unite(int a, int b) {
 P[root(a)] = root(b);
}

int main() {
 int n, q;
 cin >> n >> q;
 for (int i = 0; i<n; i++) {
  P[i] = i;
 }
 for (int i = 0; i<q; i++) {
  int com, x, y;
  cin >> com >> x >> y;
  if(com) {
   if(is_same_set(x,y)) { cout << 1 << endl; }
   else { cout << 0 << endl; }
  }
  else {
   unite(x, y);
  }
 }
}
