I have a feeling I would love this mission, if only I could figure out what to do.

Let's take the first example.

>>> int.from_bytes('hello'.encode(), byteorder='big')
448378203247

First, how do I determine the slashes? I guess 4/48, but then what? 37 is again ascending, same as 48. Or do I just put /3/7? But then the sole digit is both ascending and descending.

And then, how to actually get from there to

{4: {4: {8: {3: {7: {0: {4: {}, 7: {}}, 
                     2: {2: {}}
                    },
                 8: {3: {}}
}   }   }   }   }

? I really have no idea. How can 44837 be one branch, and then 8 be on another??
