Description
Kourindou sells $n$ kinds of items, numbered $1,\dots,n$. The price of item $i$ is $a_i$.
Kourindou has launched $m$ promotions. Each promotion can be described by three numbers $x,y,k$, meaning:
- You can pay $k$ yuan at Kourindou and exchange item $x$ for item $y$.
Now you do not have any item sold by Kourindou. For every $i$ ($1 \le i \le n$), compute how many different plans there are to spend no more than $P$ yuan, buy any one item, and then exchange it into item $i$.

> Two plans to obtain an item are considered different if at least one of the following holds:

> - During the process of turning the initially purchased item into item $i$, the promotions used are different.
The answer may be very large. Output it modulo $998244353$.
Input Format
The first line contains three integers $n,m,P$, representing the number of items sold by Kourindou, the number of promotions, and the amount of money you have.
The second line contains $n$ integers $a_1,\dots,a_n$, representing the prices of the $n$ items.
The next $m$ lines each contain three integers $x,y,k$ describing a promotion, meaning you can pay $k$ yuan at Kourindou and exchange item $x$ for item $y$.
Output Format
Output $n$ integers. The $i$-th integer is the number of plans to spend no more than $P$ yuan to buy any one item and then exchange it into item $i$, modulo $998244353$.
Explanation/Hint
**Sample Explanation**
Here we take the number of plans to obtain item $4$ as an example. The number of plans to obtain item $4$ is $2$.
Plan 1: Buy item $4$ directly, spending $4$ yuan.
Plan 2: Buy item $2$ and exchange it into item $4$, spending $4$ yuan.
**Constraints**
For $5\%$ of the testdata, $n,m \le 5$ and $P = 1$.
For $25\%$ of the testdata, $n,m,P \le 5$.
For $50\%$ of the testdata, $n,m,P \le 100$.
For another $25\%$ of the testdata, it is guaranteed that no item can be exchanged into itself after several exchanges.
For all testdata, $1 \le n \le 1000$, $1 \le m \le 3000$, and $1 \le a_i,P \le 2 \times 10^4$.
For a promotion, $1 \le x_i,y_i \le n$, $x_i \not = y_i$, and $1 \le k_i \le 2 \times 10^4$.
