Problem:
Disjoint Set

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.

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.

Constraints

1 ≤ n ≤ 10000

1 ≤ q ≤ 100000

x ≠ y

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

public class Main {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);

        int n = sc.nextInt();
        int q = sc.nextInt();

        int[] sets = new int[n];
        for (int i = 0; i < n; i++) {
            sets[i] = i;
        }

        for (int i = 0; i < q; i++) {
            int com = sc.nextInt();
            int x = sc.nextInt();
            int y = sc.nextInt();

            if(com == 0) {
                for (int j = 0; j < n; j++) {
                    if(sets[j] == sets[y]) {
                        sets[j] = sets[x];
                    }
                }
            } else {
                if(sets[x] == sets[y]) {
                    System.out.println(1);
                } else {
                    System.out.println(0);
                }
            }
        }
    }
}
