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

0 2 3

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

Sample Output

Solution in Ruby (judge verdict: Wrong Answer)

lines = $stdin.read

array = lines.split("\n")

n = array[0].split(" ")[0].to_i
q = array[0].split(" ")[1].to_i

it = -1
id = Array.new(n){it+=1}

for i in 1..q
  com = array[i].split(" ")[0]
  x   = array[i].split(" ")[1].to_i
  y   = array[i].split(" ")[2].to_i

  if com == '0'
    # id[x] ???????´???§ id[y] ???????´??????¨??????????????????
    for j in 0..n
      id[j] = id[x] if id[j] == id[y]
    end
  else
    puts id[x] == id[y] ? "1" : "0"
  end
end
