I need help in this problem. I have tried all the test cases on Udebug as well, they are passing. But Vjudge is not accepting my code.



import java.io.DataInputStream; import java.io.FileInputStream; import java.io.IOException; class Investigation { static class Reader { final private int BUFFER_SIZE = 1 << 16; private DataInputStream din; private byte[] buffer; private int bufferPointer, bytesRead; public Reader() { din = new DataInputStream(System.in); buffer = new byte[BUFFER_SIZE]; bufferPointer = bytesRead = 0; } public Reader(String file_name) throws IOException { din = new DataInputStream(new FileInputStream(file_name)); buffer = new byte[BUFFER_SIZE]; bufferPointer = bytesRead = 0; } public String readLine() throws IOException { byte[] buf = new byte[64]; // line length int cnt = 0, c; while ((c = read()) != -1) { if (c == '\n') break; buf[cnt++] = (byte) c; } return new String(buf, 0, cnt); } public int nextInt() throws IOException { int ret = 0; byte c = read(); while (c <= ' ') c = read(); boolean neg = (c == '-'); if (neg) c = read(); do { ret = ret * 10 + c - '0'; } while ((c = read()) >= '0' && c <= '9'); if (neg) return -ret; return ret; } public long nextLong() throws IOException { long ret = 0; byte c = read(); while (c <= ' ') c = read(); boolean neg = (c == '-'); if (neg) c = read(); do { ret = ret * 10 + c - '0'; } while ((c = read()) >= '0' && c <= '9'); if (neg) return -ret; return ret; } public double nextDouble() throws IOException { double ret = 0, div = 1; byte c = read(); while (c <= ' ') c = read(); boolean neg = (c == '-'); if (neg) c = read(); do { ret = ret * 10 + c - '0'; } while ((c = read()) >= '0' && c <= '9'); if (c == '.') { while ((c = read()) >= '0' && c <= '9') { ret += (c - '0') / (div *= 10); } } if (neg) return -ret; return ret; } private void fillBuffer() throws IOException { bytesRead = din.read(buffer, bufferPointer = 0, BUFFER_SIZE); if (bytesRead == -1) buffer[0] = -1; } private byte read() throws IOException { if (bufferPointer == bytesRead) fillBuffer(); return buffer[bufferPointer++]; } public void close() throws IOException { if (din == null) return; din.close(); } } public static void main(String[] args)throws IOException { Reader s=new Reader(); int test=s.nextInt(); int c=1; while(test--!=0){ char a[]=Long.toString(s.nextLong()-1).toCharArray(); char b[]=Long.toString(s.nextLong()).toCharArray(); int m=s.nextInt(); if(m>=100){ System.out.println("Case "+c+": 0"); c++; continue; } long r=solve(b,m); long l=solve(a,m); // System.out.println(l+" "+r); long ans=r-l; System.out.println("Case "+c+": "+ans); c++; } } public static long solve(char a[],int m){ int n=a.length; long dp[][][][]=new long[n+1][m][m][2]; dp[0][0][0][1]=1; for(int i=1;i<=n;i++){ int cd=a[i-1]-48; for(int p=0;p<=9;p++){ for(int j=0;j<m;j++){ int nj=(j*10+p)%m; for(int k=0;k<m;k++){ int nk=(k+p)%m; if(p<cd){ dp[i][nj][nk][0]+=dp[i-1][j][k][0]+dp[i-1][j][k][1]; } else if(p==cd){ dp[i][nj][nk][0]+=dp[i-1][j][k][0]; dp[i][nj][nk][1]+=dp[i-1][j][k][1]; } else{ dp[i][nj][nk][0]+=dp[i-1][j][k][0]; } } } } } return dp[n][0][0][1]+dp[n][0][0][0]; } }

First of all, you say your code isn't being accepted. What is the verdict? Wrong answer/RTE/TLE? What do you want us to be looking for here?

Second, have you tried writing a brute forcer to generate a break case? It is quite easy to write a naive O(biggestNumber) solution that just checks every number in the range. In the future, please at least try writing a naive solution to find an obvious break case before DMing me and posting a blog asking others to debug your code.

    It is saying wrong answer sir. Secondly, as I said I just wanted to check if the java submission is getting accepted or not, as I have tried various test cases on Udebug, and my outcome matches expected outcome.

      What do you mean you 'want to check if it is getting accepted'? If it is getting wrong answer as you said, then it isn't getting accepted.
