Coding Round
The thinking is what is scored — write the approach before the code.

JavaScript runs in your browser. Python can be traced or predicted here; the approach review still scores the thinking. No code is uploaded unless you explicitly request an AI review.
Hint ladder — one nudge at a time
- Restate the input, the output and one example before choosing a data structure.
- Name the slow solution and its cost first. Then ask what you would look up to avoid repeating work.
- Test the empty input, one item, duplicates and the maximum size. The edge is usually the question.
Complexity question: say the time and space cost of both your first idea and your final one, in one line each.
Solution walkthrough after you submit
A strong submission has four lines: the brute-force approach and its cost, the improved idea, the edge cases tested, and one trade-off you chose. Compare your approach paragraph with those four lines before you retry.
Reading your answer…
This tool runs on Way2Fresher's own engine: a question bank and a visible rubric. No API key is needed.
How it works
- Pick a problem and a language.
- Write the approach in plain words, then the code in the editor.
- Run the visible tests. Hidden tests check the edges after you submit.
- Read the walkthrough and the complexity note, then retry the weakest problem.
What you get
- In-browser editor with JavaScript and Python execution against visible tests.
- Hidden tests after submit, so passing the happy path is not enough.
- A hint ladder that gives one nudge at a time.
- Timer, topic tags and a complexity question.
- Approach review scored on thinking, structure and edge cases — not syntax alone.
- A solution walkthrough after submission.
- For other languages: output prediction and pseudocode tracing instead of execution.
- No code is sent to a server unless the site has an AI provider configured and you agree.
What a review looks like
- Approach 85: brute force named first, then the hash-map improvement and its O(n) cost.
- Edge cases 50: empty array and duplicate values mentioned; maximum size not tested.
- Visible tests 4/4 · hidden tests 2/3 · the failing case is an empty array.
Questions freshers ask
Which languages can I run?
JavaScript and Python run in your browser. For other languages, write pseudocode or predict the output; the review still scores your approach.
Is my code sent anywhere?
No code goes to a server by default. If the site has an AI provider configured and you choose AI review, the code is sent for that one review.
Can I use this for a non-coding role?
Yes. The problems are about structuring an approach and handling edges, which is useful for analyst and testing rounds too.
Do hidden tests use the same examples?
No. They check empty inputs, one item, duplicates and maximum size. Passing them means your solution generalises a little.
Can I print the review?
Yes. Use the print button on the report for a clean PDF, including your approach and the test summary.
