Problem Statement

You have a string S of length N. Initially, all characters in S are 1s.

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.
