Sharpen your Git Version Control skills with targeted coding flashcards.
Git is a distributed version control system that tracks changes in source code during software development, allowing multiple developers to collaborate efficiently.
It stores snapshots of files over time, enabling branching, merging, and reverting changes.
Use the command git init in the root directory of your project.
This creates a hidden .git subdirectory containing all repository data.
git clone <url> creates a copy of an existing remote repository on your local machine.
It includes all branches, tags, and history.
git add <file> stages changes in the working directory for the next commit.
You can stage all changes with git add . or specific files.
git commit -m "message" saves the staged changes to the local repository as a snapshot.
The commit message should describe the changes concisely.
git status shows the state of the working directory and staging area.
It lists modified, untracked, and staged files.
git log displays the commit history, including commit hashes, authors, dates, and messages.
Use options like --oneline or --graph for compact views.
The working directory is the filesystem where you edit files and where Git tracks changes.
It contains files checked out from the repository.
The staging area holds a snapshot of changes ready to be committed.
Changes must be added here with git add before committing.
A commit is a snapshot of the entire repository at a point in time, identified by a unique SHA-1 hash.
It includes metadata like author, date, and message.
git branch <branch-name> creates a new branch pointing to the current commit.
Use git checkout -b <branch-name> to create and switch to it.
git checkout <branch> switches to the specified branch.
For files, it restores them from the index or a commit.

Programming is one of the most valuable and versatile skills in the modern economy. Whether you're a bootcamp graduate solidifying fundamentals, a CS student preparing for exams, or a developer prepping for FAANG interviews, these flashcards help you master the concepts that separate junior developers from senior engineers — algorithms, system design, and software architecture.
After reviewing an algorithm or data structure card, implement it from scratch in your preferred language to build muscle memory.
For every algorithm, know its Big O time and space complexity — this is the most commonly tested concept in technical interviews.
Focus on recognizing problem patterns (sliding window, two pointers, dynamic programming) rather than memorizing individual solutions.
Yes, our programming decks cover algorithms, data structures, and system design concepts frequently tested in technical interviews at top companies.
Our flashcards focus on language-agnostic concepts, but examples reference popular languages like Python, JavaScript, Java, and C++.
We offer decks from introductory programming concepts to advanced topics like distributed systems and compiler design.
Our flashcards cover concepts in Python, JavaScript, Java, C++, Go, and more, with language-agnostic cards on algorithms and design patterns.
Yes, we have extensive coverage of arrays, linked lists, trees, graphs, sorting algorithms, dynamic programming, and complexity analysis.
Absolutely — our decks focus on the algorithmic patterns, system design concepts, and problem-solving frameworks tested at top tech companies.
