I am also having the same problem. Apparently there is no input when I check. I tried using both Scanner and BufferedReader.

I had this problem on FANCY and HP18

this is the error code for Scanner

Exception in thread "main" java.util.NoSuchElementException
at java.util.Scanner.throwFor(
at java.util.Scanner.nextInt(
at java.util.Scanner.nextInt(
at Main.main(

while using any reader, say buffered reader please check for null value being read

BufferedReader s = new BufferedReader(new InputStreamReader(;
String S=s.readLine();
if (S != null && !S.trim().equals(""))
{ // in this way u may proceed
//write your code here }

@adeepgarg4 this makes no sense. so I should ignore the first input as it might be null? how would I know how many nulls I would get, and what should I do if I get it later in the code? I’m not following what i’m supposed to do.

@keloy I think you probably did mistake in your main logic may be you trying to access at that limit which is out of input string limit…just carefully read what i said…because i did same mistake before
