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.
I used variable name abbreviations and removed some unnecessary lines. I also eliminated intermediate variables that were not necessary and condensed the return statement into a single line.

The changes were made to improve the simplicity, readability, and efficiency of the code, which in turn enhances its quality and maintainability. They were also done with the aim of optimizing the code for use in situations where large amounts of data are handled or high performance in data processing is required.
