Coding Practice
The coding round is where most placement funnels narrow hardest. These are the problems companies actually set, run against real test cases in the browser.
Get started freeWhat coding practice gives you
Five languages, in the browser
C, C++, Java, Python and JavaScript, with nothing to install.
Graded on real test cases
Including the edge cases that fail a solution which looked correct.
Organised by pattern and company
Because coding rounds repeat patterns, and the pattern is the transferable part.
How it works
- 1Pick a topic, a pattern, or a company.
- 2Write your solution in the in-browser editor.
- 3Run it against the test cases.
- 4Read the editorial for anything you could not finish.
