# SOLUTION

#### What’s in it for you?

The idea behind these programming contests is that we want you to learn while competing. Also we believe that it is alright to refer to tutorials, books and other materials, learn a concept and then apply the same to solve a problem during a contest. But it is not alright to copy other people’s solutions or seek other people’s help to solve a problem without understanding it.

The dividing line may seem to be thin but it can be captured by the spirit of learning. If whatever you are doing is making you learn while you do so, we tend to believe that it is alright. Our sole intention lies in making our users learn new concepts while competing. However, all the participants are expected to abide to

• Users are ranked according to the most problems solved. Ties will be broken by the total time for each user in ascending order of time.
• The total time is the sum of the time consumed for each problem solved. The time consumed for a solved problem is the time elapsed from the beginning of the contest to the submittal of the first accepted run plus 10 penalty minutes for every previously rejected run for that problem. There is no time consumed for a problem that is not solved.
