Wrong return value

I''ve submitted an old AC code, however on the new judge the verdict is runtime error, because I've returned by 1 instead of 0 from the int main() routine. I've checked and there are lots of such codes, probably hundreds. It would be great to modify all codes by judge to avoid such problems.

10290 Huge time limit, but why?

Ok, I know that all time limits are 3/10 on the new judge as it was on the old judge. But I'm sure that for example on this problem it's too large. Now it is 33.333 sec., however today I've solved it in 0.02 sec. Looking the old stats 29 people solved it in 10 seconds (on the new judge this would be...

Slow loading time and km long judge queue!

Do you know what happens on these days? Yesterday it took me about half an hour to load a single page on acm uva, today at least the last 50 submissions, and probably much more are in the judge queue. It can be the most popular programming site. But my guess, that not so longer, if there are such an...

Re: 10218 - Let's Dance!!

Here it is the exact values for the sample input:

Code: Select all

f(10,20,20)=1743392201/3486784401
f(10,20,7)=1094/2187
As you can see in the first testcase the result is very close to 0.5, but it is differ from that in reality.

Re: All time limits are 0.0 sec. on the 200-th contest!

It is sad that it took about 45 minutes to observe this obvius error. It' raising many questions: 1. who has added all time limits=0.0 sec? 2. why nobody read the problem description from acm uva? 3. why they haven't seen the submissions page? (all codes were TLE) 4. why it took almost an hour to de...
