Community problems

Problems written by solvers on Robols Math, reviewed before they go live and credited to the person who proposed them.

Anyone with an account can propose a problem: their own, or one from a contest the archive does not have yet. A reviewer checks the statement, the answer and the solution, sets a starting difficulty, and publishes it. The proposer's solution becomes the first comment, and the problem's source line names them.
