Problem:
 Score : 100 points    Problem Statement You are given an array a_0, a_1, ..., a_{N-1} of length N . Process Q queries of the following types.   0 l r b c : For each i = l, l+1, \dots, {r - 1} , set a_i \gets b \times a_i + c .  1 l r : Print \sum_{i = l}^{r - 1} a_i \bmod 998244353 .       Constraints  1 \leq N, Q \leq 500000  0 \leq a_i, c < 998244353  1 \leq b < 998244353  0 \leq l < r \leq N  All values in Input are integer.         Input Input is given from Standard Input in the following format:  N  Q  a_0  a_1 ... a_{N - 1}  \textrm{Query}_0  \textrm{Query}_1 : \textrm{Query}_{Q - 1}       Output For each query of the latter type, print the answer.
