 > [!TIP]
 > If a day has different example inputs for both parts, you can use the `read_file_part()` helper in your tests instead of `read_file()`. For example, if this applies to day 1, you can create a second example file `01-2.txt` and invoke the helper like `let result = part_two(&advent_of_code::template::read_file_part("examples", DAY, 2));` to read it in `test_part_two`.
