Implement the LRU Cache with O(1) time complexity for get and put operations.
class LRUCache<K, V> {
private capacity: number;
private map = new Map<K, V>();
constructor(capacity: number) {
this.capacity = capacity;
}
get(key: K): V | undefined{
if (!this.map.has(key)) return undefined;
const val = this.map.get(key)!;
this.map.delete(key);
this.map.set(key, val);
return val;
}
}$ run test-suite --verbose

✓ Test 1: Instantiation pass (2ms)
✓ Test 2: O(1) Get & Put pass (1ms)
✓ Test 3: Eviction order pass (3ms)
Result: 3/3 Tests Passed (100%)
Engineered for Hands-on Code Mastery
Discover the building blocks that empower students to learn by doing, and enable trainers to deliver high-impact evaluations.
Multi-Language Coding
Native execution support across 24 programming languages. Run code instantly with integrated compilers, runtimes, and WebAssembly tooling.
Coding Labs
Structured, curriculum-driven coding environments tailored for students and trainers. Includes problem briefs, starter code, and test criteria.
Browser Playground
A fast, distraction-free playground for rapid experimentation, algorithmic testing, and quick code sharing without configuring a local dev environment.
Public & Private Labs
Explore community-shared public labs or keep proprietary training modules secure within private organisation workspaces.
Assignments & Submissions
Students complete coursework, run test verifications, and submit solutions directly through the lab interface with automated timestamps.
Trainer Review & Grading
Trainers inspect student code submissions, evaluate execution output, verify test pass rates, and deliver actionable evaluations.
Progress Tracking
Clear visibility for both learners and educators. Track completed assignments, pending reviews, active labs, and overall curriculum milestones.
Real-Time Notifications
Automated platform alerts keep everyone in sync when assignments are published, submissions are made, reviews are completed, or invitations arrive.
24 Supported Languages Out of the Box
Compiled and interpreted directly with instant browser execution and server-backed runners.
Purpose-Built for Students, Trainers, and Organisations
Each participant gets dedicated interfaces, workflows, and permissions tailored to their role in the learning process.
Learn, experiment, and prove your engineering skills
Access guided, structured coding labs with clear objectives, constraints, and instructions.
Write, run, and experiment with code across 24 languages with zero local machine configuration.
Work on structured problems and test logic against test criteria before final submission.
Submit work directly from the coding workspace with automated status tracking.
Monitor your assignments, submission statuses, scores, and trainer feedback in one place.
Receive real-time notifications on assignment reviews, trainer notes, and new lab releases.

EditorCode eliminates the friction of local software installations. Whether you are exploring Public Labs, working through an assigned Private Lab, or testing ideas in the freeform Playground, the experience is instant, isolated, and feature-rich.
Full Multi-File Projects
Navigate source files, configuration manifests, and test suites with a clean file tree explorer.
Virtual Terminal & Output Stream
Inspect compiler diagnostics, stdout logs, stderr error traces, and test results in real-time.
Public & Private Workspaces
Open access community labs for independent practice, paired with private labs for restricted company training.

A streamlined, cohesive journey from curriculum authoring to verified evaluation.
Trainer Creates Lab
The trainer configures a new coding lab with starter files, problem instructions, supported language runtime, and assignment criteria.
Student Opens Lab
Enrolled students access the assigned lab or explore public labs. The browser workspace initializes immediately with zero setup required.
Student Writes & Tests Code
The student develops their solution, executes code in real-time, inspects terminal logs, and iterates using the built-in browser runtime.
Student Submits Assignment
Once tests pass, the student submits their solution. The system records the submission timestamp and notifies the assigned trainer.
Trainer Reviews Submission
The trainer views the submitted code, evaluates test results, adds constructive feedback, and marks the assignment status.
Clear Visibility Across Every Submission and Metric
Real-time tracking of assignment submissions, trainer grading velocity, and learner curriculum completion.
Submission Status Tracking
