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 PYTHON3):

Solution:
class DisjointSet:
    def __init__(self, n):
        self.p = [x for x in range(n)]
        self.rank = [0 for x in range(n)]

    def find_set(self, x):
        if self.p[x] != x:
            self.p[x] = self.find_set(self.p[x])
        return self.p[x]

    def link(self, x, y):
        if self.rank[y] < self.rank[x]:
            self.p[y] = x
        else:
            self.p[x] = y
            if self.rank[x] == self.rank[y]:
                self.rank[y] += 1

    def union(self, x, y):
        self.link(self.find_set(x), self.find_set(y))

    def same(self, x, y):
        return (self.find_set(x) == self.find_set(y))

n, q = list(map(int, input().split()))

S = DisjointSet(n)

for i in range(q):
    com, x, y = list(map(int, input().split()))
    if com == 0:
        S.union(x, y)
    elif com == 1:
        if S.same(x, y):
            print(1)
        else:
            print(0)
