You are given a tree with $n$ nodes, numerated from $0$ to $n-1$. For each $k$ between $0$ and $n$, inclusive, you have to count the number of unordered pairs $(u,v)$, $u \neq v$, such that the MEX of all the node labels in the shortest path from $u$ to $v$ (including end points) is $k$.
The MEX of a sequence of integers is the smallest non-negative integer that does not belong to the sequence.
Input
The first line contains a single integer $t$ ($1 \le t \le 10^4$) — the number of test cases.
The first line of each test case contains a single integer $n$ ($2 \le n \le 2 \cdot 10^{5}$).
The next $n-1$ lines of each test case describe the tree that has to be constructed. These lines contain two integers $u$ and $v$ ($0 \le u,v \le n-1$) denoting an edge between $u$ and $v$ ($u \neq v$).
It is guaranteed that the given edges form a tree.
It is also guaranteed that the sum of $n$ for all test cases does not exceed $2 \cdot 10^{5}$.
Output
For each test case, print $n+1$ integers: the number of paths in the tree, such that the MEX of all the node labels in that path is $k$ for each $k$ from $0$ to $n$.
Note
- In example case
$1$,
- For
$k = 0$, there is$1$path that is from$2$to$3$as$MEX([2, 3]) = 0$.- For
$k = 1$, there are$2$paths that is from$0$to$2$as$MEX([0, 2]) = 1$and$0$to$3$as$MEX([0, 2, 3]) = 1$. - For
$k = 2$, there is$1$path that is from$0$to$1$as$MEX([0, 1]) = 2$. - For
$k = 3$, there is$1$path that is from$1$to$2$as$MEX([1, 0, 2]) = 3$ - For
$k = 4$, there is$1$path that is from$1$to$3$as$MEX([1, 0, 2, 3]) = 4$.
- For
- In example case
$2$,
- For
$k = 0$, there are no such paths.- For
$k = 1$, there are no such paths. - For
$k = 2$, there is$1$path that is from$0$to$1$as$MEX([0, 1]) = 2$.
