If getline() fails, we should free the pre-allocated line buffer to avoid memory leaks. If line is NULL, calling free(NULL) is safe according to the C99 specification (Section 7.20.3.2). This ensures proper memory management in case of input failure. Co-authored-by: charliechiou <charlie910417@gmail.com>
