RXD has a polynomial function $f(x)$, $f(x) = \sum_{i = 0}^{n}{c_ix^i}$
RXD has a transformation of function $Tr(f, a)$, it returns another function $g$, which has a property that $g(x) = f(x - a)$.
Given $a_1, a_2, a_3, \dots , a_m$, RXD generates a polynomial function sequence $g_i$, in which $g_0 = f$ and $g_i = Tr(g_{i - 1}, a_i)$
RXD wants you to find $g_m$, in the form of $\sum_{i = 0}^{m}{b_ix^i}$
You need to output $b_i$ module 998244353.
