Since during hacking we face such a solution sometimes which is likely to pass for small test cases and would definately fail for larger test cases sometimes its in type of array so suppose upto 1e6 .Then in that case since codeforces editor doesn't allow copy paste operation during hacking and we can't type such 1e6 numbers for just one hack and in a short duration. So can anybody knows solution of this or any method by which we we can hack that solution?? thanks in advance.. :)
