Thinking through test cases and understanding the behavior of the program can help identify potential off-by-one errors and prevent them from occurring. It is important to consider edge cases and think about how the program will behave under different inputs. Randomly inserting +1 or -1 is not a reliable strategy and can lead to incorrect results. Starting a loop at 0 may not always be appropriate and avoiding the < operator altogether may limit the flexibility of the code.
