Description:

This version of the problem differs from the next one only in the constraint on $$$n$$$.

A tree is a connected undirected graph without cycles. A weighted tree has a weight assigned to each edge. The distance between two vertices is the minimum sum of weights on the path connecting them.

You are given a weighted tree with $$$n$$$ vertices, each edge has a weight of $$$1$$$. Denote $$$d(v)$$$ as the distance between vertex $$$1$$$ and vertex $$$v$$$.

Let $$$f(x)$$$ be the minimum possible value of $$$\max\limits_{1 \leq v \leq n} \ {d(v)}$$$ if you can temporarily add an edge with weight $$$x$$$ between any two vertices $$$a$$$ and $$$b$$$ $$$(1 \le a, b \le n)$$$. Note that after this operation, the graph is no longer a tree.

For each integer $$$x$$$ from $$$1$$$ to $$$n$$$, find $$$f(x)$$$.

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 $$$n$$$ ($$$2 \le n \le 3000$$$).

Each of the next $$$n−1$$$ lines contains two integers $$$u$$$ and $$$v$$$ ($$$1 \le u,v \le n$$$) indicating that there is an edge between vertices $$$u$$$ and $$$v$$$. It is guaranteed that the given edges form a tree.

It is guaranteed that the sum of $$$n$$$ over all test cases doesn't exceed $$$3000$$$.

Output:

For each test case, print $$$n$$$ integers in a single line, $$$x$$$-th of which is equal to $$$f(x)$$$ for all $$$x$$$ from $$$1$$$ to $$$n$$$.

Sample Input:

Sample Output:

1 2 2 2 
1 1 
2 2 3 3 3 3 3

Note:

$\text{[math]}$ In the first testcase:

For $$$x = 1$$$, we can an edge between vertices $$$1$$$ and $$$3$$$, then $$$d(1) = 0$$$ and $$$d(2) = d(3) = d(4) = 1$$$, so $$$f(1) = 1$$$.
For $$$x \ge 2$$$, no matter which edge we add, $$$d(1) = 0$$$, $$$d(2) = d(4) = 1$$$ and $$$d(3) = 2$$$, so $$$f(x) = 2$$$.
