Can someone point out the mistake in my code? It is giving the following error on big inputs:

Exception in thread "main" java.lang.StackOverflowError
	at Main.solve(Java_Script_2.java:41)

Code:

dp[n][dig] is the number of integers with n digits left and the previous digit(the digit to the left) is dig.

import java.io.BufferedReader;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.util.StringTokenizer;
 
class Main {
    private static final int mod = 1000000007;
    static class Reader {
        private BufferedReader br;

Did you find the bug in your code? I am having the same problem.

Can someone point out the mistake in my code, it fails at only test case #10.
