#D7116. Disjoint Set: Union Find Tree
Disjoint Set: Union Find Tree
Disjoint Set: Union Find Tree
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
