Level of difficulty of problems-[admin]

Some of you may get stuck with certain problems on this Online Judge platform and feel frustrated to move forward.

Mr. Wong is planning to give an estimated level of difficulty to each problem. Problems of 1* are the simplest. If you fail to solve a difficult problem, you may skip it, finish other problems, and try it again later.
