#D7166. Replace Digits
Replace Digits
Replace Digits
You have a string S of length N. Initially, all characters in S are 1
s.
You will perform queries Q times. In the i-th query, you are given two integers L_i, R_i and a character D_i (which is a digit). Then, you must replace all characters from the L_i-th to the R_i-th (inclusive) with D_i.
After each query, read the string S as a decimal integer, and print its value modulo 998,244,353.
Constraints
- 1 \leq N, Q \leq 200,000
- 1 \leq L_i \leq R_i \leq N
- 1 \leq D_i \leq 9
- All values in input are integers.
Input
Input is given from Standard Input in the following format:
N Q L_1 R_1 D_1 : L_Q R_Q D_Q
Output
Print Q lines. In the i-th line print the value of S after the i-th query, modulo 998,244,353.
