814 - The Letter Carrier's Rounds

[Dominik Michniewski]

Could anyone help me and post some tricky IO for this problem ?
What should I print in such cases:
1 - MTA of sender doesn't exist. Should I print "connection between ..." or not ?
2 - mail sender doesn't exist in MTA ?

Any help would be great

Best regards
DM

Did you consider this line in the output section?

Also a message is addressed to the same user only once.

Hello all,

still can't figure out why 814 was not accepted. Have found here that you have to check for duplicate recipients: "z@z.com z@z.com". But no one mention about another problem - you also have to check for more than one spaces between recipients:

Now instead of WA I've received Presentation Error. Where/Why, please somebody help me.

Thank you in advance!

I have found world Finals Solution:
http://contest.mff.cuni.cz/archive/finl1999/

but even this solution gives WA...

If you get a PE, check this statement in the description:

No innecessary spaces should be printed

It turns out that the message may contain trailing spaces that you need to remove.
Also, if after you remove trailing spaces, the line of message is empty, then you don't print the 5 spaces.

By the way, the world finals solution for that site gives WA for a couple of the problems, so don't take it seriously.
