@sunny0712 use try & catch blocks whenever using Scanner class as i/p

You might be trying to take input when it doesn’t even exists like your program would be reading 6 numbers when there would exist only 5 in the input. Check your loops in which you are taking input and also check whether you are providing the right input data.

Its coz of improper formatting of inputs by codechef like extra space or carriage return etc.

I had really bad experience due to this

Solution is not to read it int by int but rather read complete line and then split the string

String[] st = br.readLine().split(" ");

Don’t use scanner for cp. Its too slow. use bufferedReader
