Sorting algorithms
& Big O Notation


This project aims to learn about the main sorting algorithms: Bubble Sort, Insertion Sort, Selection Sort and Quick Sort; while evaluating the time and space complexity of each designed algorithm and the Big O notation in C language.

Overview

Holberton School teaches Full-Stack Software Engineering with a project-based approach. Sorting algorithms & Big O Notation is one of the main projects of the second trimester that covers the High-level programming of Software Engineering.

Requirements

To run the algorithms you need to download the code files by clicking Download sorting_algorithms. Or by cloning this repository with the following command in your command terminal. The result will be the same regardless of the option you choose.

~$ git clone https://github.com/viajeradelaluz/sorting_algorithms.git

The compilation process uses GNU Compiler Collection (GCC) and a Linux environment like Ubuntu 20.04 LTS. Enter the sorting_algorithms folder and use the makefile as follows.

Invocation

Each invocation of the make command executes a different algorithm with its respective printout on the console.

0. Bubble Sort

The 0-bubble_sort.c function sorts an array of integers in ascending order using the Bubble sort algorithm.

~/sorting_algorithms$ make bubble
