  • GitHub repo interviews

    Everything you need to know to get the job. (by kdn251)

    Project mention: Free Computer Science Resources with Interview Prep and much more... | dev.to | 2021-03-29


  • GitHub repo Java

    All Algorithms implemented in Java

    Project mention: Any beginner-friendly tutorials on hashing +salting strings? | reddit.com/r/learnjava | 2021-03-27

    here you can use of the ciphers

  • GitHub repo Javascript

    A repository for All algorithms implemented in Javascript (for educational purposes only) (by TheAlgorithms)

    Project mention: Useful GitHub repositories for learning Web Development | dev.to | 2021-02-17

    4. The Algorithms - JavaScript

  • GitHub repo C

    Collection of various algorithms in mathematics, machine learning, computer science, physics, etc implemented in C for educational purposes. (by TheAlgorithms)

    Project mention: Algorithms by Jeff Erickson (Free algorithms textbook) | news.ycombinator.com | 2021-02-08

    I like the awesome-algorithms link, but some of the code linked is definitely not perfect. A few questionable things from one of the header files [0] in https://github.com/TheAlgorithms/C:

    - Defines a macro with no parentheses

    - Uses unsigned for length and capacity (should be size_t)

    - Uses () instead of (void) for an empty parameter list

    - Useless use of "extern" for function declarations

    - I think that leading double underscores and structures ending with _t are reserved identifiers, but I don't really have a good source for this

  • GitHub repo aoc

    🎄 My solutions and walkthroughs for Advent of Code (https://adventofcode.com) and more related stuff.

    Project mention: Peter Norvig's “pytudes” for Advent of Code 2020 | news.ycombinator.com | 2021-01-05

    If you like this, you will love https://github.com/mebeim/aoc/tree/master/2020

    The guy created very clean python solutions, and very insigthful walkthrough (although a bit wordy some times). It was my go to repo after validating my solutions on AoC (he managed to publish daily during the whole challenge !).

  • GitHub repo cpalgorithms

    Algorithms and Techniques for competitive programming

    Project mention: Hacktoberfest: 69 Beginner-Friendly Projects You Can Contribute To | dev.to | 2020-09-29

    https://github.com/namanvats/cpalgorithms Algorithms and Techniques for competitive programming

  • GitHub repo BitsPlease-solutions

    Solutions For Problems uploaded in

    Project mention: The story behind my first ever pull request | dev.to | 2020-10-12

    The PR

  • GitHub repo DataStructure

    I will build the logic, code and then debug the coding problems in my youtube series of #LogicCodeDebug. So, this is going to be a step by step solution of coding problems. I believe, everyone has it's own way of learning. For few problems, it's easy to understand by just seeing the Logic but for few we need to debug them.

    Project mention: [3] Step by Step solution | Find the Second Largest element in array using C# | Java | dev.to | 2021-01-26

    Git Links: C#: https://github.com/kushalseth/DataStructure/blob/master/CodingProblems/CodingProblems/ArrayProblems/SecondLargestInArray.cs
