Coding Practice

A collection of code challenges and computer science topics

Purpose

• Clean Code notes, examples and checklist.
• Algorithms for searching and sorting.
• Data Structures like Singly Linked List, Doubly Linked List, Heaps and Trees.
• Solving Patterns like Divide and Conquer, Multiple Pointers and Frequency Counter.
• System Design documents including a checklist.
• Codewars Code Challenges
• Leetcode Code Challenges
• Other Code Challenges

Built With

• The code is written using Javascript, Typescript and Python.
• The Typescript tests are written with Jest for unit testing.

Getting Started

For Typescript Challenges

1. Install using npm i command in your terminal.

2. Run npm run test-ts <filename> for a specific test, or npm run test-ts to run all tests.

For Python Challenges

1. Install using pipenv install command in your terminal.

2. Start a shell environment by running pipenv shell

3. Navigate into any directory and run files using the python <filename> command.

4. Alternative for automatically rerun tests: Install nodemon globally: npm i -g nodemon and then run KYU=<kyu> FOLDER=<folder> KATA=<kata> npm run test-py. The first three variables (e.g. KYU=6KYU FOLDER=arrayDiff KATA=array_diff) define which test to run.
