Problem Statement
You are given an integer sequence $A = (A_1, A_2, \ldots, A_N)$ of length N.
We will perform the following operation on A for $i = 1, 2, \ldots, M$ in this order.
- First, choose an integer between L_i and R_i, inclusive, uniformly at random and denote it as p.
- Then, change the value of A_p to the integer X_i.
For the final sequence A after the above procedure, print the expected value, modulo 998244353, of A_i for each $i = 1, 2, \ldots, N$.
How to print expected values modulo 998244353
It can be proved that the expected values sought in this problem are always rational. Furthermore, the constraints of this problem guarantee that if each of those expected values is expressed as an irreducible fraction $\frac{y}{x}$, then x is not divisible by 998244353. Now, there is a unique integer z between 0 and 998244352, inclusive, such that xz $\equiv y \pmod{998244353}.$ Report this z.
Input
The input is given from Standard Input in the following format:
N M
$A_1 A_2 \ldots A_N$
L_1 R_1 X_1
L_2 R_2 X_2
$\vdots$
L_M R_M X_M
Output
Print the expected values E_i of the final A_i for $i = 1, 2, \ldots, N$ in the format below, separated by spaces.
$E_1 E_2 \ldots E_N$
Constraints
- All input values are integers.
- $1 \leq N, M \leq 2 \times 10^5$
- $0 \leq A_i \leq 10^9$
- $1 \leq L_i \leq R_i \leq N$
- $0 \leq X_i \leq 10^9$

We start from the initial state A = (3, 1, 4, 1, 5) and perform the following two operations.
- The first operation chooses A_1 or A_2 uniformly at random, and changes its value to 2.
- Then, the second operation chooses one of A_2, A_3, A_4 uniformly at random, and changes its value to 0.
As a result, the expected values of the elements in the final A are $(E_1, E_2, E_3, E_4, E_5) = (\frac{5}{2}, 1, \frac{8}{3}, \frac{2}{3}, 5)$.
