using namespace std;
int a,b,c;
int par[10005];
int find(int p){
    if(par[p]==0){
        return p;
    }
    par[p]=find(par[p]);
    return par[p];
}
int main(){
    int n,m;
    scanf("%d%d",&n,&m);
    for(int i=0;i<m;i++){
        scanf("%d%d%d",&a,&b,&c);
        if(a==1){
            par[find(b)]=find(c);
        }
        else{
            if(find(b)==find(c)){
                cout<<"Y"<<endl;
