to judge online team, suggestion...

most times we work more on finding a way to send and make the judge online accept our answers than making the program works really good...
so, a suggestion that i am thinking is this:
when a program doenst match your database tests, u could instead of saying WRONG ANSWER tell him something like: your program failed to do this test , your answer "X" for the input "Y" is not correct, please re-make your program...
in that way u wouldnt give him the answer BUT he would see that his program has a problem with some parts of the problem universe and would try to fix it...

this is better since that WRONG ANSWER is really annoying cause we need to find WHERE is the problem without any clue...

This is what happens in a real contest, so situation is the same here. But always u have other programmers to help u out, which you will not find in real contest (other than your team mates). We are actually trying to make a contest like environment here. But if you go through this web board and the old web board you will find hints on many of the critical problem.

well, lemme give u an example , i think i had solved the problem 294..
all my solutions r the same as a friend of mine X did... however the judge online doesnt accept my program giving me a wrong answer but my friends get`s accept...
we tested both our programs , checked the answers using the DIFF command of linux and they r the same... so, i would like to know where my program is wrong...
thats a case judge online doenst cover up... so, thats why i am giving this sugestion, if the judge told me YOUR PROGRAM DIDNT ANSWER THE INPUT "X" CORRECTLY i would know the problem, however, i dont know it until now...

Try the following input with your and your friend's program:

1000
1 1
2 2
3 3
4 4
5 5
6 6
. .
. .
. .
(I think you get the idea)

Maybe your program have some non-initialized variables, what's wrong only for special cases, when they have no new values. In many environment it has a zero value, what's good for your program too, so the outputs will be totally ok. Except, if your program runs under linux. If your program hasn't got this mistake, let you think about mistakes like it. Maybe your program has Segmentation Fault, what does not cause problem in your system and the judge's sytem too, but in the judge's system you write over an other important variable => WA.
