There is a tree(the tree is a connected graph which contains $n$ points and $n-1$ edges),the points are labeled from 1 to $n$,which edge has a weight from 0 to 1,for every point $i\in[1,n]$,you should find the number of the points which are closest to it,the clostest points can contain $i$ itself.
the first line contains a number T,means T test cases.
for each test case,the first line is a nubmer $n$,means the number of the points,next n-1 lines,each line contains three numbers $u,v,w$,which shows an edge and its weight.
$T\le 50,n\le 10^5,u,v\in[1,n],w\in[0,1]$
for each test case,you need to print the answer to each point.
in consideration of the large output,imagine $ans_i$ is the answer to point $i$,you only need to output,$ans_1~xor~ans_2~xor~ans_3..~ans_n$.
1 2 0
2 3 1
in the sample.
$2~xor~2~xor~1=1$,so you need to output 1.
