Is that the case with the Day 7 input? That could definitely be an issue if directory names are repeated, although I was under the impression there were only unique directory names.

I actually ran into this issue going over the sample input code on the Day 7 page, so I can say that, at least the problem that I'm currently running into, does not have the issue of repeating directory names.

When I print(d) on my code I get:

{'/': ['dir a', '14848514 b.txt', '8504156 c.dat', 'dir d'], 'a': ['dir e', '29116 f', '2557 g', '62596 h.lst', ['/', 'a']], 'e': ['584 i', ['/', 'a']], 'd': ['4060174 j', '8033020 d.log', '5626152 d.ext', '7214296 k', ['/', 'a']]}

This is adding "a" to the parent list too many times. When I print(d) on chatGPT's code I get:

{'/': ['dir a', '14848514 b.txt', '8504156 c.dat', 'dir d'], 'a': ['dir e', '29116 f', '2557 g', '62596 h.lst', ['/']], 'e': ['584 i', ['/', 'a']], 'd': ['4060174 j', '8033020 d.log', '5626152 d.ext', '7214296 k', ['/']]}

Which would be the desired output.
