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 Python3 (judge verdict: Accepted)

def find(x):
    if tree[x] < 0:
        return x
    tree[x] = find(tree[x])
    return tree[x]


def unite(x, y):
    x_position = find(x)
    y_position = find(y)
    if x_position == y_position:
        return True
    if y_position < x_position:
        x_position, y_position = y_position, x_position
    tree[x_position] += tree[y_position]
    tree[y_position] = x_position
    return False


def same(x, y):
    if find(x) == find(y):
        print(1)
    else:
        print(0)


n, q = map(int, input().split())
tree = [-1] * n
for i in range(q):
    com, x, y = map(int, input().split())
    if com == 0:
        unite(x, y)
    if com == 1:
        same(x, y)
