List three controls that could be applied to detect or prevent off-by-one errors

Input validation: Implementing input validation checks on user input can help detect off-by-one errors. For example, if the user is asked to enter a quantity, the input validation code can check that the value entered is not negative or greater than the maximum allowed.

Code review: Conducting code reviews with a focus on off-by-one errors can help prevent such errors. Code reviewers can check for loops, arrays, and other constructs that could be prone to off-by-one errors and ensure that they are coded correctly.

Automated testing: Writing automated tests can help detect off-by-one errors. These tests can be designed to test edge cases and boundary conditions, which are often where off-by-one errors occur. Automated tests can also be run frequently to catch any new off-by-one errors that might be introduced during code changes
