🧰 Algo - Cheat Sheet

Motivation

While I studied at university I realized, that In theory there is no difference between theory and practice, but in practice there is.

Theory and practice:

• Theory: everything is clear, but nothing works
• Practice: everything works, but nothing is clear
• Sometimes theory meets practice: nothing works and nothing is clear

The purpose of this project is mainly to keep my analytics skills up to date and enhance them as well. Of course, the data structures and algorithms are always fun, but sometimes they can be very difficult in other words this repo can be something like a "fast" lookup for interview preparation.

Currently, I plan to add content that touches data structures and a lot of algorithms gathered from platforms like LeetCode, Codility end etc.

Requirements

• Node ^18.14.2
• NPM ^9.5.0

Installation

After confirming that your environment meets the above requirements, it is time to clone the project locally by doing the following:

$ git clone [email protected]:DeanHristov/algo-cheat-sheet.git <project-name>
$ cd <project-name>

When you're done with the steps above, you need to install the project dependencies.

$ npm install

Running the Project

In order to run the code in dev mode. Go to in your project (root) directory and follow the command below.

$ npm run dev

Testing

Currently, the project is supporting unit testing with JEST. In order to run them you have to perform:

$ npm test

Main tasks

All tasks automation are based on NPM scripts.

Tasks	Description
npm run start	Running the code in dev mode
npm run lint	Analyzing the code for problems with eslint
npm run prettier-format	Code formatting
npm run test	Running the unit tests ( using jest)
npm run test:watch	Running the unit tests in "watch" mode
npm run test:coverage	Running the coverage of the unit tests
