Test a custom input to verify an edge case (e.g. empty lists, negative numbers, duplicates).
This bug belongs to the logic errors pattern
The wrong operator, an inverted condition, a formula the right way round but backwards.
What went wrong: Removing items from a list while iterating over it shifts the internal index, causing the loop to skip the next item.
The fix: Filter the list without in-place mutation using a list comprehension: [num for num in numbers if num % 2 != 0]
Remember: Never mutate a list in-place while iterating over it in a for loop.
The pattern behind it: logic errors.
