There is no contest before 29th,April.Wouldn't it be nice to have a contest before "Educational Round-108"?

It's almost impossible to prepare the problemset for a round in 5 days.
You can do some virtual participation instead.
Isn't it better to have a "Div-3" Round?
Div-3 problems are easier to solve, but that does not mean they are easier for problem setters.
At first, there is some work have to be done for every problem, even A+B. You'll have to write and test validator, checker, and the correct solution very carefully. Just writing them like solving a problem in contest won't work: for example it should be forbidden to use
scanf
in a validator or checker, as it invokes undefined behavior for bad inputs. And you'll have to find a group of people to test the problem. The construct of test input is tricky: randomly generated inputs aren't sufficient for many problems.And it's actually more difficult to make a problem suitable for less experienced participants, as the problem has to be creative and interesting (i. e. it shouldn't be a duplicate of a well-known problem, or the contest will become "Google contest": test who can use Google better :).
Some problems may be even much more difficult to set than solve, especially in constructive problems. If the model solution to a complicated problem is to output
1
and then2
n-1 times, solutions will most likely be easy to code, but the checker may require advanced data structures and algorithms for efficiency.Yes. It'd be very nice indeed. Would you consider authoring a Div. 10 round for us?
