This is your pitch and your proof. Be specific. If your approach is counter-intuitive, say so here.
Declaration of originality

Read before checking. The platform's rules on plagiarism are non-negotiable. If you worked with AI tools, that's fine — describe it in your approach. If you collaborated with others, they are co-solvers and share the prize equally if you win.

I declare that this solution is my original work (or my team's original work), produced for this challenge. It does not plagiarize any prior submission, published work, or the work of others without attribution. I understand that a false declaration disqualifies my entry and may result in a permanent ban from the platform. I have read and agree to the platform rules.
If you win
Winners are the best proof the platform works. Your story helps the next solver believe they can win too.
Your entry is timestamped the moment it's received. You may refine and resubmit until the deadline — the most recent submission counts.
