Your public coding profiles, read automatically and mapped against your own batch — with the next problem to solve.
How it works
Scroll through the four steps, or grab the map and turn it. Every column is a topic; every ring is your batch.
Drag, use arrow keys or the turn buttons to turn · hover or tab to a column to read it
Representative data · not a real profile
Add your usernames. We read four public profiles — never a password, never the code you write.
Every topic becomes a column. Its height is what you have actually solved, read automatically and stored with its date.
The ring on each column is your batch median. Columns that stop below their ring are your gaps — they light up.
The deepest gap becomes your next move. Here that is dynamic programming, 2.2 problems below the batch median — chosen by comparison, not by a model guessing.
