If this ever gets approved, someone will have to check if random tests in all languages generate compliant inputs.

Don't just make up specs that were not there before!

Thank you for the explanation!

Can someone please explain how does this work?

Especially the 4th line: "if c in r:" and so on.

Thanks!

Cant really say this is pythonic - especially the naming of variables shouldnt be one character.

Thanks, forgot about this.

Very understandable and efficient, I likes it.

That's a cool little method, that I somehow managed to miss while reading the documentation. Thanks for posting it!

hmmmm

It looks like best pracices...

Kevin is noticing his space run out!
Write a function that return array of connected words in each element of array as in example below.
For example, running this function on the array ['i', 'have','no','space'] would return ['i','ihave','ihaveno','ihavenospace'].
P.S. data input will be only words with no special signs.

seriously ?
