Hi!
I have spaces left, that's the reason my output isn't correct.
Thanks!

hint (maybe): you DO return a list of multiline strings, not a list of lists of string as shown above?

Ah, didn't know that. So, must be because of left or extra spaces: I'll check it out again.
Thanks for your help!

That does not change anything because your output is sorted before it's compared to the expected solution.

Hi everybody!
I have one question:

why for this input:

               "+-------------------+--+", 
               "|                   |  |",
               "|                   |  |",
               "|  +----------------+  |",
               "|  |                   |",
               "|  |                   |",
               "+--+-------------------+"])

The expected output is this one:

                   "                 +--+",
                   "                 |  |",
                   "                 |  |",
                   "+----------------+  |",
                   "|                   |",
                   "|                   |",
                   "+-------------------+"]),
                 ["+-------------------+",
                   "|                   |",
                   "|                   |",
                   "|  +----------------+",
                   "|  |",
                   "|  |",
                   "+--+"])]

And not this one (which, btw it's my program exit)?:

                  ["+-------------------+",
                   "|                   |",
                   "|                   |",
                   "|  +----------------+",
                   "|  |",
                   "|  |",
                   "+--+"])]
                   
                   "                 +--+",
                   "                 |  |",
                   "                 |  |",
                   "+----------------+  |",
                   "|                   |",
                   "|                   |",
                   "+-------------------+"]),     

What's the rule? I understood that you read from left to right and the output contains the figures read from left to right, am I wrong?

Cheers and Thanks
