I deleted function arranged_problems and now when I use print(arithmetic_arranger([“3 + 4855”, “3801 - 2”, “45 + 43”, “123 + 49”, “3801 - 2”], True)) for example or print(arithmetic_arranger([“3 + 4855”, “3801 - 2”, “45 + 43”, “123 + 49”, “3801 - 2”])). Everything is printed correctly. But when I post code in test It fails again. Don’t know where is problem really. (posting code without calling function ofc)

```
