I would suggest try compiling it with codeforces compiler which is there under custom invocation tab. Check whether that gives any error.

I played around with your code and found it was a problem with your reader. Somehow messed up the reference data. Your code using BufferedReader instead: 193524061. Just stick with BufferedReader and PrintWriter for now. You don’t need any fancy readers on problems like these. If you want a good fast reader for java you can look at this guide: https://usaco.guide/general/fast-io?lang=java

If you log the chars the program reads at the readLine() function, you will get '1', '\r', '\n' (and it returns "1\r"). Therefore, your program prints "1\r\r1".
