How can I find out whether the problem is a Special Judge Problem or NOT ? Do there are any common condition or specification for identifying this type of problem ? Thanks in advance.

What does special judge problem mean?
I think he means Interactive Problems. Although I could be wrong.
What is Interactive Problem?
A problem with many different possible solutions . ( May Be)
Oh. There's no specification for that. Those problems can be found readily on CodeForces only. Just go to a2oj.com, start doing any A/B/C ladder, and you'll find a heck lot of problems having many possible solutions, and we got to print any one of them.
It's usually written in the statement.
I didn't get it written in CF 359 B -_-
Note
Note that you don't have to minimize the number of operations. Any solution that performs at most 20 000 operations is allowed.
Except it is.
