Algorithms & Interview Prep
Free · In‑App Purchases
Practice 52 data structures and algorithms challenges with guided hints, custom tests, step-by-step debugging, detailed results, and an offline Dart guide.
Build practical data structures and algorithms skills with focused coding challenges. ByteKata takes you from approachable warm-ups to demanding interview-style problems while keeping your work organized in a distraction-free mobile workspace. Solutions are written and tested in Dart.
PRACTICE INTERVIEW SKILLS
- Solve 52 challenges organized into 13 focused chapters
- Progress through beginner, easy, medium, and hard difficulty
- Study arrays, strings, hashing, linked structures, stacks, heaps, trees, binary search trees, graphs, backtracking, dynamic programming, sliding windows, and more
- Learn frequently asked patterns alongside less familiar techniques worth knowing
STAY FOCUSED ON MOBILE
- Move quickly between the problem, code editor, and test results
- Keep Run and Submit within reach while you write code
- Return directly to the relevant source location when an error includes a line and column
- Preserve your code and place as you move between sections
WRITE, RUN, AND DEBUG
- Work in a purpose-built editor with line numbers and syntax highlighting
- Run visible tests or create custom test cases with JSON inputs
- Compare actual and expected results, then reveal hidden test details when needed
- Keep diagnostic print output separate from the returned answer
- Investigate compile and runtime errors with available line and column details
- Watch supported solutions execute step by step
LEARN AS YOU GO
- Use a concise Dart reference for variables, conditions, loops, strings, character codes, lists, maps, collection methods, sorting, custom comparators, math functions, and more
- Reveal progressive hints only when you ask for them
- Unlock a worked explanation and reference solution after completing a challenge
- Move freely between the challenge workspace and the Dart reference
KEEP YOUR WORK
- Save progress and code drafts locally
- Export or import progress and saved code as a JSON backup
- Recheck every saved solution after evaluator updates
- Practice offline after installation without creating an account
FREE AND PREMIUM ACCESS
The first challenge in every chapter is included. A single optional non-consumable Premium purchase unlocks the remaining challenges in all current and future chapters. Previous purchases can be restored from Settings.
ByteKata is designed for deliberate practice: understand the problem, form an approach, test the edge cases, and refine the code.
