Read the rules again:

• Fit as many words as you can on a single line.
• Always try to break on spaces.

hello is 5 char long not 7, that confuses me

For the sample test ("this is a test", 4) , it says that the output should be "this\nis a\ntest" - this is wrong?? Instead should it not be "this\nis\natest"?

hello and world are two words, the limit is per line. "hello world" is 11 chars long, so your function should break it, what's misleading?

In the sample tests for python there is this example:
("hello world", 7) -> "hello\world"
Am I wrong or the counting here is misleading?
Obviously hello doesn't match the 7 limit.
This confusions sadly deter me from attempting the challenge
