This is the exact type of problem where being precise about your string validation is a good thing.

That check is a waste of time for such a petty problem like this.

Check the failure, i suppose there is a "1234 ".
There is a " " at the end. And it's on new line.

Почему то выдает ошибку: Wrong output for '1234': expected false to equal true.
Пин 1234 не проходит по условию
