Priya solved it in 14:22.

Every solve is timed. Solves synced from LeetCode are verified, and the rest say self-reported, so nobody has to take anyone's word for it.

Stuck? You get a question, not the code.

Sarathi, your guide, nudges in steps you choose. It never writes the solution for you.

A challenge is one problem, one time to beat, one friend. Beat it and they hear about it.

Fourteen days. Nobody has missed one.

A squad streak only counts the days everyone solved. Not a sum of five solo streaks: one streak, kept together.
