Hi,

Anyone finished A3 with full mark?

I was stuck by some performance issue. My filter was always timeout:


[Test Description] filter: tweet with 321 retweets
[Observed Error] Test timeout: aborted after 30 seconds; Check for infinite loops!
  [exception was thrown] detailed error message in debug output section below
[Lost Points] 10

I couldn't find more efficient way to implement it. Any hint?

Thanks.

自己给自己解答吧……原来是因为另一个方法union的原因，真是奇怪了，明明filter没用到union。

Great.
No, I've found out where the problem was. It's because my union implementation-I just used the one which had been showed in the lecture : P . After changing to use tail and head, the exception was gone.
