Yes mine failed with price = 54 discount = 5 holiday_cost = 8856

This will FAIL in some cases, i did it like this, but division in python using // is not always precise, use with care

PD: I was getting an error but attempt it until a random case didn´t break my code :-)

my boh

Thank you)

999 needs to be padded up with zeros to have a total of 4 digits (the "length" of the original number), i.e.,
999 -> 9990.

And so
9990-0999 => 8991

When i tried to attempt, i got number 2111.
It's:
2111 - 1112 = 999
999 - 999 = 0
-> -1 ,
but the correct answer is 6.
Help, pls.
It happens on second test.
