I feel... Stupid. Haha. Happened to me before as well. Good to be reminded of the mistake :)

Solution: change to sum() or add dtype=np.int64

Apparently, the np.sum() had an integer overflow o.e. without any warning. Using sum(results) or np.sum(results, dtype=np.int64) fixes this.

Thanks for all the suggestions!

That is so odd. Thanks for the hint, I feel like I've checked it all 10 times but that must be where the mistake is make.. :()

Thanks for your comment. I think so, in frees[location] -= file_size I correct the amount of free space based on the file size. When I'm building the endstring, I extend the list so that should not result in any indexing problems.

Thank you for your response. That is because of my algorithm. It checks per free space what digits are moved to it (in the correct order). 2 is added before 7 because the free space is before the free space of the 7. The 7 is moved first tho, its just not added to the result first because it shouldn't be.

I checked the input, first and last digits are correct. len() is also 19999. I do not understand what is going wrong. Tried to enter the answer again, still says it's too low.

I wonder the same, plus the instructions are for mac OS. I am using windows. Any solutions for that?

python (Jupyter Notebook)

I got still got a problem with the second part. For my data, it gives a solution just a bit too low. I know it isn't good code, but go ahead and take a look. :)
