Code can be a piece of art

Hey! My name is Ohav. Sometimes I may write an article on something that interests me, but **coding** is something I always do!

ohaval / counting_sort.py

Created May 7, 2024 19:06

An implementation of the counting-sort algorithm, including time complexity stats showing O(n)

	"""A python example which shows the time complexity of the counting sort algorithm (O(n + k)).

	The final output is a table showing the execution time of the counting sort algorithm for lists of different lengths.
	Copied from my execution on my machine:

	524288 (2**19) -> 0.25
	1048576 (2**20) -> 0.49
	2097152 (2**21) -> 0.92
	4194304 (2**22) -> 1.75
	8388608 (2**23) -> 3.47

ohaval / sort_five_elements_seven_comparisons.py

Created May 5, 2024 08:34

An implementation of the Ford-Johnson Algorithm for a 5 integer list in Python, which sorts in 7 comparisons only

	"""As part of the 'Data Structures and Introduction to Algorithms' course, I was asked to solve the following problem:
	Write a function that sorts five elements in seven comparisons in the worst case.

	As I found this problem interesting, I decided to implement it in Python. For better understanding, I recommend
	reading the answer from the link below, which explains the algorithm.
