blhack: I can't reply to your comment so am posting here. It would work like this: 1. You need to have a solution repository. 2. Developers post solutions there. For instance, find numbers less than n where the sum of divisors is greater than number but none of the divisor subset equals the number. And the solution is tagged with the implementation language. 3. Before posting a question, someone can look into the repository and get the solution from there if already there. What problem it solves: 1. Developers can post their solutions without someone asking for it. 2. Solution seekers will have a smaller turnaround time if the solution is already there in the repository.
