Maybe one boat is in contact with anyother boat ,you can limit the number of 1

Looks resolved, right?

Not exactly, this time:

Pause between characters inside a word – is 3 time units long.
Pause between words – is 7 time units long.

So the code there doesn't show spaces as the previous kata. Look at the binary code below, you'll see time unit is 2 and there is a bunch of 14 zeroes that represent the space.

^ That.

111 in binary is 7 in base 10. (not divisble by 3)

oh, that is actually way simpler than that. The problem is on your side:

Matches should be case-insensitive, and the words in the result should be lowercased.

okay. Can you give me your output on those, please?

please, provide meaningful informations:

• input ?
• exact assertion message error?

I like the way this is done but not sure about changing the actual source string using replace.

I get your frustration. I too read the problem in the "sensible way". Just accept that it wasn't intended to have any real-life useful meaning, and it's basically a sequence-manipulation trick. Either bit the bullet or skip the kata (I wouldn't blame you, it's just my OCD keeping me here)

Fixed :)

What language ?

This is difficult to do properly I think. Server load varies. If it's done right, then I'm all for it.

Please read the description more carefully...

• Clones do my kata
• Then they sleep (and they lose ability when they sleep)
• Then (if they can) they re-clone

So if they could do only 1 Kata.. then after they've slept then they cannot do any Kata, and so they cannot re-clone either.

Q.E.D.

Thats great idea!It would make learning proccess much more enjoyable.
