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.

Sarai vs. Kadafi - Fizzbuzz

Shorter but not necessary as readable. I chose to break the line at what i would consider each thought. Like an "if, else"
"If #calculations# is true? Do this. Otherwise keep going"
"If #calculations# is true? Do this. Otherwise keep going"
"If #calculations# is true? Do this. Otherwise keep going"
Chould definitely be a oneliner, but in my opinion oneLiners makes it less readable which will make it harder for the next programmer to understand.

Find the Unique

You are given an array with N numbers. N - 1 numbers are the same. You must find the unique number.

  • The input array will always have at least 3 numbers.
  • The input array can be very large. Be mindful of performance.

DO NOT USE GOOGLE!!!

DO NOT LOOK AT OTHER SUBMISSIONS!!!

DO NOT EDIT THE TEST CASES!!!
