The only difference between easy and hard versions is constraints.

Nauuo is a girl who loves random picture websites.

翻译中…

One day she made a random picture website by herself which includes $n$ pictures.

翻译中…

When Nauuo visits the website, she sees exactly one picture. The website does not display each picture with equal probability. The $i$-th picture has a non-negative weight $w_i$, and the probability of the $i$-th picture being displayed is $\frac{w_i}{\sum_{j=1}^nw_j}$. That is to say, the probability of a picture to be displayed is proportional to its weight.

翻译中…

However, Nauuo discovered that some pictures she does not like were displayed too often.

翻译中…

To solve this problem, she came up with a great idea: when she saw a picture she likes, she would add $1$ to its weight; otherwise, she would subtract $1$ from its weight.

翻译中…

Nauuo will visit the website $m$ times. She wants to know the expected weight of each picture after all the $m$ visits modulo $998244353$. Can you help her?

翻译中…

The expected weight of the $i$-th picture can be denoted by $\frac {q_i} {p_i}$ where $\gcd(p_i,q_i)=1$, you need to print an integer $r_i$ satisfying $0\le r_i \lt 998244353$ and $r_i\cdot p_i\equiv q_i\pmod{998244353}$. It can be proved that such $r_i$ exists and is unique.

Input

翻译中…

The first line contains two integers $n$ and $m$ ($1\le n\le 2\cdot 10^5$, $1\le m\le 3000$) — the number of pictures and the number of visits to the website.

翻译中…

The second line contains $n$ integers $a_1,a_2,\ldots,a_n$ ($a_i$ is either $0$ or $1$) — if $a_i=0$ , Nauuo does not like the $i$-th picture; otherwise Nauuo likes the $i$-th picture. It is guaranteed that there is at least one picture which Nauuo likes.

翻译中…

The third line contains $n$ positive integers $w_1,w_2,\ldots,w_n$ ($w_i \geq 1$) — the initial weights of the pictures. It is guaranteed that the sum of all the initial weights does not exceed $998244352-m$.

Output

翻译中…

The output contains $n$ integers $r_1,r_2,\ldots,r_n$ — the expected weights modulo $998244353$.

Note

翻译中…

In the first example, if the only visit shows the first picture with a probability of $\frac 2 3$, the final weights are $(1,1)$; if the only visit shows the second picture with a probability of $\frac1 3$, the final weights are $(2,2)$.

翻译中…

So, both expected weights are $\frac2 3\cdot 1+\frac 1 3\cdot 2=\frac4 3$ .

翻译中…

Because $332748119\cdot 3\equiv 4\pmod{998244353}$, you need to print $332748119$ instead of $\frac4 3$ or $1.3333333333$.

翻译中…

In the second example, there is only one picture which Nauuo likes, so every time Nauuo visits the website, $w_1$ will be increased by $1$.

翻译中…

So, the expected weight is $1+2=3$.

翻译中…

Nauuo is very naughty so she didn't give you any hint of the third example.
