Why a solution which got Accepted during the online contest should get WA now?

Because the admins forgot to add the special judge for this problem, so currently it only accepts output which is identical to the judge output.

Yes, you are right, this issue is fixed. Yesterday I wrote an email to the admins about it.

I submit my code to the new system.
I had wait for 10 minutes and the new online-judge system still shows these information in "My Submissions" page:
Code: Select all
# Problem Verdict Language Run Time Memory Used Submission Time
5909477 Get Straight C++ 2007-09-10 06:53:50
I don't know what's wrong to my code or to the new online-judge system.

I have passed all the random input from udebug. But I am still getting WA.
Can someone provide more random inputs?
- 7D TD 5C 4H AC
AD 8H TS JH 5H
#
My output for the above list is:
Exchange TD
Exchange AD
The output from udebug is:
Exchange AC
Exchange 5H
Can someone tell me why is there a difference between my output and udebug's output? The expected value for both outputs are the same.

If there is more than one optimal strategy for a given deal, print any one of them. A special judge will evaluate your output.

What is the output for:
I get "Stay" but on uDebug I get "Exchange 9H". According to my calculation staying is better than exchanging 9H. Am I missing something?

If you stay with that input, you'll have a Dutch so end up losing 1.
If you exchange one of the 9's, you'll have a:
4/47 chance of getting a 8 and a Double Dutch, win 1
4/47 chance of getting a 10 and an Invite-the-Neighbours, win 10
3/47 chance of getting a Q and a Double Dutch, win 1
4/47 chance of getting a K and a Menage-a-Trois, win 3
Expected earning of: 4/47 * 1 + 4/47 * 10 + 3/47 * 1 + 4/47 * 3 - 2 = -35/47 = -.74 dollar, which is better than staying at -1.

I didn't handle duplicates.
My code just count them as once. (But still regard them as 2 or more cards.)
For your input 4H 4H 5H 3H 3H
My program gives stay.
PS. I'm also from Taiwan. Nice to meet you.

I ignore the suit and only look at the value of each card. You're right there are cases where cards are duplicated, but there are no cases where there are 5 cards with the same value.
