Problem H. Win Strategy
*****
What is the time contest starts - is it 0 or 1? I mean that if L is the length, then when the contest will finish, at minute L or L+1?
Contest starts at the beginning of the first minute (minute 1). And it ends at the end of minute L. When a problem becomes available, it will be available in the beginning of the minute, so you can start solve it in the same minute.

Problem H. Win Strategy
*****
If a problem is solved at time L
shall it be considered ?
or all the problem should be solved before L ?
The contest length is L and the first minute is 1. 
Solving a problem starts at the beginning of a minute and takes bi continuous minutes, so if solving a problem finishes at the end of minute L then it is considered in the number of problems solved.
