Hi, I'm Pablo, the creator of impol.dev.
Understanding a DSA explanation and writing a working solution are different skills. I built impol.dev to help developers connect the two through video lessons and hands-on practice.
You can write solutions directly in the browser, try test cases, and submit your code for evaluation. The demo shows that flow through to an Accepted result.
Some lessons and hundreds of problems are free. There's also optional paid Premium access to more content.
I'd appreciate feedback on the first learning session: is it clear where to start and what to do after watching a lesson?
Thanks for taking a look!
