PLATFORM CAPABILITIES
A practice environment
built around progress.
These are the planned / expected capability areas. Features that depend on the live coding engine will be available only once the platform has been implemented and connected.
Online code editor
Write, run and test solutions in supported languages, with readable input/output and execution feedback.
Test cases & submissions
Validate solutions against test cases, review accepted or failed submissions and revisit attempts.
Topic-wise practice
Build a consistent DSA journey across arrays, strings, linked lists, stacks, queues, trees, graphs, dynamic programming and more.
Contests & timed assessments
Practice under time limits with scheduled contests, classroom assessments and coding tests.
Progress dashboard
Track attempted problems, solved questions, accuracy and topic-level progress where the connected platform supports it.
College / instructor workflows
A planned workflow for instructors to assign practice, conduct assessments and review student results.
Fair assessment controls
Configurable assessment rules and integrity monitoring, depending on the deployed platform and institutional requirements.
