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 n,q,c,x,y,p[10010];

void init(int n){
    for(int i=0;i<n;i++){p[i]=i;}
}

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(){
    cin>>n>>q;
    init(n);
    for(int i=0;i<q;i++){
        cin>>c>>x>>y;
        if(c){cout<<is_same_set(x,y)<<endl;}
        else{unite(x,y);}
    }
}
