For a tree $$$T$$$ with $$$n \ge 2$$$ vertices, consider the standard process for generating its Prufer sequence. We repeatedly perform the following steps until only two vertices remain:

Select the leaf with the smallest label;
Remove it from the tree.

It is known that vertex $$$n$$$ is always one of the two remaining vertices. Let $$$v$$$ be the other remaining vertex. We define the Prufer vertex of $$$T$$$ as $$$P(T) = v$$$.

You are given a forest with $$$n$$$ vertices and $$$m$$$ edges. Let $$$k$$$ be the number of connected components in this forest, and let their sizes be $$$s_1, s_2, \ldots, s_k$$$. It is known that there are exactly $$$n^{k - 2} \prod\limits_{i=1}^k s_i$$$ ways to add edges to the forest so that it becomes a single tree.

For each $$$v$$$ ($$$1 \le v \lt n$$$), calculate how many of these ways result in a tree $$$T$$$ satisfying $$$P(T) = v$$$.

Since the answers can be large, print them modulo $$$998\,244\,353$$$.

Input

Each test contains multiple test cases. The first line contains the number of test cases $$$t$$$ ($$$1 \le t \le 10^4$$$). The description of the test cases follows.

The first line of each test case contains two integers $$$n$$$ and $$$m$$$ ($$$2 \le n \le 2 \cdot 10^5$$$, $$$0 \le m \le n - 1$$$) — the number of vertices and edges in the forest, respectively.

The next $$$m$$$ lines of each test case contain two integers $$$u$$$ and $$$v$$$ ($$$1 \le u, v \le n, u \neq v$$$), describing an edge between vertices $$$u$$$ and $$$v$$$. It is guaranteed that these edges form a forest (that is, the graph is acyclic).

It is guaranteed that the sum of $$$n$$$ over all test cases does not exceed $$$2 \cdot 10^5$$$.

Output

For each test case, print $$$n - 1$$$ integers on a single line. The $$$i$$$-th integer should be the number of ways to add edges to the forest so that it becomes a tree $$$T$$$ satisfying $$$P(T) = i$$$, modulo $$$998\,244\,353$$$.

Note

In the first example, there are no edges in the forest, and there are $$$3$$$ ways to complete it to a tree. One of them is to add edges $$$(1, 2)$$$ and $$$(1, 3)$$$. There are $$$2$$$ leaves: vertex $$$2$$$ and $$$3$$$. Since $$$2$$$ has a smaller label, it gets deleted from the tree, and only two vertices remain: $$$1$$$ and $$$3$$$. Therefore, the Prufer vertex of this tree is $$$1$$$.

In the third example, the forest is shown below:

$\text{[math]}$

Suppose we add edges $$$(3, 5)$$$ and $$$(3, 1)$$$ to complete it to a tree $$$T$$$. It is going to look like this:

$\text{[math]}$

It can be shown that $$$P(T) = 1$$$.
