( 260 ) G Another Meme Problem PROGRAMMING dp 3000

B"Let's call a fraction frac{x}{y} good if there exists at least one another fraction frac{x'}{y'} such that frac{x}{y} = frac{x'}{y'} , 1 <= x', y' <= 9 , the digit denoting x' is contained in the decimal representation of x , and the digit denoting y' is contained in the decimal representation of y . For example, frac{26}{13} is a good fraction, because frac{26}{13} = frac{2}{1} . You are given an integer number n . Please calculate the number of good fractions frac{x}{y} such that 1 <= x <= n and 1 <= y <= n . The answer may be really large, so print it modulo 998244353 . The only line of the input contains one integer n ( 1 <= n < 10^{100} ). Print the number of good fractions frac{x}{y} such that 1 <= x <= n and 1 <= y <= n . The answer may be really large, so print it modulo 998244353 . "...
