This submission is migrated from previous version of oj.uz, which used different machine for grading. This submission may have different result if resubmitted.
// Sample grader for contestants' use.
//
// Usage: place your input data in the file password.in in the format
//
// line 1: N S
// line 2: hidden_password
//
// Then compile this grader together with your implementation.
// Run the binary to see your guessing strategy at work!
// Set DEBUG to 1 to print all queries.
