Kumite (ko͞omiˌtā) is the practice of taking techniques learned from Kata and applying them through the act of freestyle sparring.
You can create a new kumite by providing some initial code and optionally some test cases. From there other warriors can spar with you, by enhancing, refactoring and translating your code. There is no limit to how many warriors you can spar with.
A great use for kumite is to begin an idea for a kata as one. You can collaborate with other code warriors until you have it right, then you can convert it to a kata.

For example,
[True, True, True, False,
True, True, True, True ,
True, False, True, False,
True, False, False, True ,
True, True, True, True ,
False, False, True, True]
The correct answer would be 17.
Hint: Don't forget to check for bad values like null/undefined

luckily no is a prodigy in coding and knows how to make string arrays in the form of sentences
turn no's arrays into sentences
ex.

"the dog is brown"
