Steps

  • Winter Term 2024

    Bring ideas to life

    It begins with a vision: create an innovative learning platform for the algorithms and data structures. We combine our ideas and lay the foundation.

  • Summer Term 2025

    Got it - let's go

    The project officially commences with the implementation of initial ideas. We make good progress through structured planning and efficient teamwork.

  • Winter Term 2025

    Coding hell

    The development process enters an intensive phase. Our focus is on implementation of exercises, managing technical challenges, and ensuring code quality.

  • Summer Term 2026

    Final countdown

    The final development phase comprises addition of more exercises, comprehensive testing, and optimization to ensure a seamless user experience.

  • Future Work

    Beyond Algorithms & Data Structures

    Our vision is to enhance the scope by integrating other computer science modules.
