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.

}
func shuffle(slice []int) {
rand.Seed(time.Now().UnixNano()) // seed the random number generator
for i := len(slice) - 1; i > 0; i-- {
j := rand.Intn(i + 1) // choose a random index in the slice
slice[i], slice[j] = slice[j], slice[i] // swap the elements at the two indices

Problem statement
Write a function fibonacci(n) that takes a positive integer n as input and returns the nth number in the Fibonacci sequence. The Fibonacci sequence is a series of numbers in which each number after the first two is the sum of the two preceding ones. The sequence starts with 0, 1, 1, 2, 3, 5, 8, 13, 21, and so on.
Constraints
The input integer n will be a positive integer not exceeding 50.
Notes
This problem can be solved using recursion, but using an iterative solution is also a valid approach.
function fibonacci(n) {
if (n === 0) {
return 0;
}
if (n === 1) {
return 1;
}
return fibonacci(n - 1) + fibonacci(n - 2);
}const { expect } = require('chai');

it('should return 0 for input 0', function() {
expect(fibonacci(0)).to.equal(0);
});
it('should return 1 for input 1', function() {
expect(fibonacci(1)).to.equal(1);
});
it('should return 1 for input 2', function() {
expect(fibonacci(2)).to.equal(1);
});
it('should return 2 for input 3', function() {
expect(fibonacci(3)).to.equal(2);
});
it('should return 55 for input 10', function() {
expect(fibonacci(10)).to.equal(55);
});

Background
In 1937, a German mathematician named Lothar Collatz formulated a hypothesis that still remains unproven. The algorithm can be described as follows:
-
Step 1: Take any
non-negativeinteger andnon-zerointeger and call itn. -
Step 2: if
nis even, evaluate a newnasn ÷ 2. -
Step 3: otherwise, evaluate a new
nas3 * n + 1. -
Step 4: if
ndoes not equal1, then repeat the process starting atstep 2.
Task
Write a function named collatz_conjecture. The function takes a single parameter n, which is an integer, and executes the algorithm above. The function should also count the steps needed to achieve the task. The function should return a tuple consisting of two (2)integer objects, the output of n, and the number of steps needed to execute the task, in that order. If n is not non-negative or is not a non-zero integer return n and 0.
Make the program as simple or as complex as you like; however, utilize the algorithm, and return the expected output.
def collatz_conjecture(n: int) -> int:
"""A function that utilizes Collatz Conjecture"""
if n <= 0 or not isinstance(n, int):
# If so, return n, and zero
return n
# start Collatz Conjecture
while True:
# if n equals 1, return n
if n <= 1:
break
# if n is even, divide it by 2
elif n % 2 == 0:
n //= 2
else:
# else multiply n by 3 and add 1.
n *= 3
n += 1
