could someone tell me what the test 1 is??thanks

Why should the admins keep the testcase so carefully?Is there any stupid guys prefer to Submit other's programme without his himself's effort?
  If there were,and please delete their IDs,but please just DO NOT keep the test case a forever-secret,we need them very much!!!!!!!!

I agree a lot!!
No one have the spare time to submit other's program just for the rank.It's significance.
