Wtf? Only one test case?

Testing the given tests
Sample Test OK Execution time: 0s ACCEPTED!

Why doesn z-mushrooms have only one test, aldo it is written that it has 20!

Only one sample test is tested during submission (one of the test cases given in the problem statement).

All the other cases are tested after the competition.

Great thanks!
One more Question!

Submission Stats
Task #Submissions
z-blocks 9
z-hacker 6
z-photo 5
z-mushrooms 3
z-board 2
z-matrix 1

Are these stats just for my team or for all teams comulatively?

It's for all teams. ;)

Thank you!

If I think again, I have one more question... It is written that the best solution from all members in group will count.
But, what about for a single member... Will it count just the last submission or the best one?

last one for single members
